13. Joining the frequent visitor program at the planetarium costs $5 per year, Write an equation that can be used to determine n, the number of visits per year for which the cost of being a member of the frequent visitor program is equal to the cost of not being a member. Tickets cost $11 for each student who is a member of the planetarium's frequent visitor program and $13 for each student who is not a member. 14 : Solve your equation from item 13. List a property of equality or provide an explanation for each step 15: Explain the meaning of the solution of the equation

Pleasure to meet you ^.^
shreenithaa
  • shreenithaa
u too
shreenithaa
  • shreenithaa
do u get the question, i am stumped
jennyrlz
  • jennyrlz
let me see... i will write as i read :)
shreenithaa
  • shreenithaa
k thanks for helping
jennyrlz
  • jennyrlz
planetarium program cost: 5 per yr n=visits per year perks for being a member: 2 dollars of ticket (non-memeber pirce: 13 dollars)
jennyrlz
  • jennyrlz
ok i got this information from number thirteen
shreenithaa
  • shreenithaa
k did u get the answer
jennyrlz
  • jennyrlz
working it out xD
shreenithaa
  • shreenithaa
sorry take ur time
jennyrlz
  • jennyrlz
N = llx + 13y hmm im a little confused by the question but this is what i got :)
jennyrlz
  • jennyrlz
X being the amount members visiting, and why the non members
jennyrlz
  • jennyrlz
and y*
shreenithaa
  • shreenithaa
that's what i got too but solving it was the hardest part i tried to search everywhere
jennyrlz
  • jennyrlz
to solve for it we would need to make up an x and a y
shreenithaa
  • shreenithaa
i think that x=13 and y=11 but how do you justify that that is your answer you know by using mathematical steps
shreenithaa
  • shreenithaa
it says that they have to be equal thats why
jennyrlz
  • jennyrlz
where does it say it has to be equal?
shreenithaa
  • shreenithaa
it says it on number 13
shreenithaa
  • shreenithaa
yup
jennyrlz
  • jennyrlz
ohhhhhhhhhhhhhhhhhhhh i see, i just skimmed it XD
shreenithaa
  • shreenithaa
its k
jennyrlz
  • jennyrlz
let me re make the equation then :)
shreenithaa
  • shreenithaa
k
jennyrlz
  • jennyrlz
11n = 13n
jennyrlz
  • jennyrlz
do you get it?
shreenithaa
  • shreenithaa
yeah but when it says n is the number of total visitors, it just gets confusing
jennyrlz
  • jennyrlz
ok let me explain it :)
shreenithaa
  • shreenithaa
thnx
jennyrlz
  • jennyrlz
n is the number of visitors, in other word total visitors not just members or vice versa. with me so far?
shreenithaa
  • shreenithaa
guess so
shreenithaa
  • shreenithaa
then how do you know how much n is
jennyrlz
  • jennyrlz
one sec let me finish explaining that then we will get to that :)
shreenithaa
  • shreenithaa
k
jennyrlz
  • jennyrlz
hmm let me make an analogy (a fictional example to help relate)
jennyrlz
  • jennyrlz
so if i were to try and get people to join a program i would try and show them the benefits, or how much money they can save correct?
shreenithaa
  • shreenithaa
yup
jennyrlz
  • jennyrlz
wait...
jennyrlz
  • jennyrlz
i just confused my self... let me step back andre think this from the beggining
shreenithaa
  • shreenithaa
sure
jennyrlz
  • jennyrlz
ok.. after some quick thinking ive come up with a new equation
jennyrlz
  • jennyrlz
5 + 11n = 13n
jennyrlz
  • jennyrlz
wow it makes sense now :D
shreenithaa
  • shreenithaa
yeah because of the +5 of the yearly thing but how about justifying it
jennyrlz
  • jennyrlz
with this equation we get 2.5 visits per year which is wrong.. but we are on the right tracks now!
jennyrlz
  • jennyrlz
lets make one more change to the equation
jennyrlz
  • jennyrlz
remebered i said N was the total visits correct
jennyrlz
  • jennyrlz
remember*
shreenithaa
  • shreenithaa
s remembering
jennyrlz
  • jennyrlz
this means that n can not be the same for both 11 and and 13
shreenithaa
  • shreenithaa
yeah beacuse not the same amount of people have membership and not so ur right
jennyrlz
  • jennyrlz
so the new equation is 5 +11x = N - 13y
shreenithaa
  • shreenithaa
okay
shreenithaa
  • shreenithaa
i just dont get how you will get n or x or y
jennyrlz
  • jennyrlz
hmm same... but lets ee
jennyrlz
  • jennyrlz
see
shreenithaa
  • shreenithaa
it would be easier if we knew what n was wouldn't we
jennyrlz
  • jennyrlz
hmm i just had an idea, let me try working it out on my side...
shreenithaa
  • shreenithaa
sure
shreenithaa
  • shreenithaa
i am sorry to hurry you but i need to go and could u type the answer i will check in the morning sorry i an stay for 10 minutes
jennyrlz
  • jennyrlz
Alright ill see if this idea leads to the answer :D
shreenithaa
  • shreenithaa
thns u have soooooooo much help
shreenithaa
  • shreenithaa
what grade r u in
jennyrlz
  • jennyrlz
12th
shreenithaa
  • shreenithaa
whaa... i am in 8th
jennyrlz
  • jennyrlz
but i finished highschool math last year xD
jennyrlz
  • jennyrlz
im taking college lvl math now ^.^
shreenithaa
  • shreenithaa
omg i have been waiting for colledge like forever
shreenithaa
  • shreenithaa
i cant wait to go
jennyrlz
  • jennyrlz
to think i passed calculus to be struggling on a middle school math problem u.u
jennyrlz
  • jennyrlz
college is fun :d
shreenithaa
  • shreenithaa
and hahaha well common core algebra 1
shreenithaa
  • shreenithaa
do u come home from colledge or stay there
jennyrlz
  • jennyrlz
go home
jennyrlz
  • jennyrlz
xD
shreenithaa
  • shreenithaa
oh guess that's why u r even here
shreenithaa
  • shreenithaa
gotta go
jennyrlz
  • jennyrlz
cya
jennyrlz
  • jennyrlz
I GOT ITTTTTTT
jennyrlz
  • jennyrlz
After many errors it all clicked!!!
jennyrlz
  • jennyrlz
we where right the first time! well... errr third time or whatever it was
jennyrlz
  • jennyrlz
the correct equation is 11n +5 = 13n
jennyrlz
  • jennyrlz
what we need to prove is that buying membership and paing 11 dolars or just not being a member is the same in this equation
jennyrlz
  • jennyrlz
so following the equation if you only go 2.5 times a year then it will cost you the same as if you buy membership and go 2.5 times a year
jennyrlz
  • jennyrlz
11(2.5) = 27.5 =27.5 + 5 =32.5 13(2.5) = 32.5
jennyrlz
  • jennyrlz
we did it!
jennyrlz
  • jennyrlz
i was mislead by the impossibility of visiting 2.5 times, but that doesn't matter, the question is just asking for an equation that would make it theoretically possible for them them to result in the same price!!
jennyrlz
  • jennyrlz
as for a property of equality...
jennyrlz
  • jennyrlz
we used the subtraction property of equaltiy
jennyrlz
  • jennyrlz
5+ 11n (-11n) = 13n (-11n)
jennyrlz
  • jennyrlz
subtraction equality means that if we subtract the same number to both sides we still end up with the same equations for example the equation 5=5, if we subtract the same numbeer from both sides, it will still be true. 2-5 =5-2 = 3=3
jennyrlz
  • jennyrlz
number 15 i think i answered by saying that you would have to visit 2.5 times etc....
jennyrlz
  • jennyrlz
wow that was hard! That is the most thinking ive done in a while hahaha,
shreenithaa
  • shreenithaa
thnx sooo much
shreenithaa
  • shreenithaa
u were really helpful i guess that finishing calculus really paid off huh
shreenithaa
  • shreenithaa
i finally got it and no u got the answer with the very little help i was able to give thank u sooo much that was easier than i thought wow |dw:1441805152704:dw|
jennyrlz
  • jennyrlz
Np! It was fun :P
jennyrlz
  • jennyrlz
and nice art skills :D
jennyrlz
  • jennyrlz
And calculus is never worth it xD
jennyrlz
  • jennyrlz
i even reccomend taking statistics over precalc
shreenithaa
  • shreenithaa
thnx
