Sandra uses two mobile cell phones( a digicel and a lime phone), to make her monthly calls. Sandra budget only $7000 on telephone calls per month and the cost per minute for digicel and lime are $5.00 and $7.00 respectively. a. Write down the algebraic equation for Sandra's budget constraint. b. Graph then Sandra's budget constraint. ( the budget constraint intercepts should be shown clearly on the graph) c. How will an increase in the cost per minute for digicel call affect the budget line's y_intercept, x-intercept and the slope?

a) 7000 = 5x + 7y , where x is digicel and y is lime

  • GoldRush18
i had that for a and i thought mine was wrong, now im understanding :)
anonymous
  • anonymous
it could be 7000 > 5x + 7y

because she can't go over but can be under
GoldRush18
  • GoldRush18
oh i get it
GoldRush18
  • GoldRush18
bcuz the 7000 is her budget
GoldRush18
  • GoldRush18
so wat about part b and c
anonymous
  • anonymous
part b is asking for a budget constraint line and part be also said equation for budget restraint. I would put 7000 = 7x + 5y as the answer for part a because that is the restraint line. Something that she can't go over
anonymous
  • anonymous
part b is kinda difficult. You should solve for y so the equation is in y = mx + b form then you can graph it. label your axis according to what cell phone. So if we solve for y, the y axis will be the lime phone
anonymous
  • anonymous
part c I would just pick an increased amount for the cost per minute. graph that as well, and you should easily be able to see the differences from there
anonymous
  • anonymous
let me know what you got solving for y or x and I'll check you. You should be fine from there

oh im not good at graphs thats why i need the help
GoldRush18
  • GoldRush18
ok i got y=1000 and x=1400
anonymous
  • anonymous
so those are the intercepts, What is the equation?

is it that?
anonymous
  • anonymous
7000 = 5x + 7y 7000 - 5x = 7y 1000 - (5/7)x = y The graph looks correct.
anonymous
  • anonymous
lets change the cost of digicel to 10 for easy math sake
anonymous
  • anonymous
7000 = 10x + 7y (0,1000) (700,0)

So what do you think the answers are for c
GoldRush18
  • GoldRush18
i think that as the cost per minute for digicel increase then the budget line will become steeper, is it?
anonymous
  • anonymous
Because the x and y can easily be switched between the diff cell phones make sure you are stating your assumption of what x and y are along the way. You shouldn't be wrong because it doesn't say what each should be. That is correct. Technically it gets more negative. laymen's term steeper. What about the intercepts?
GoldRush18
  • GoldRush18
ok thanks i knw what u mean but im not sure how to explain it in terms of intercepts.
anonymous
  • anonymous
Look at the lime intercept of the 2 graphs. Do they change? same for the digicel, do they change
GoldRush18
  • GoldRush18
ok the y axis which is lime does not change but the x axis which is digicel changes when price increase, im trying to answer
anonymous
  • anonymous
correct for lime, it stays the same. How does the digicel change
GoldRush18
  • GoldRush18
the digicel changes because there was an increase in the cost.
anonymous
  • anonymous
correct but in what way does it change? That is how you need to answer this question
anonymous
  • anonymous
increase of decrease
anonymous
  • anonymous
or**
GoldRush18
  • GoldRush18
oh the x intercept decreases
anonymous
  • anonymous
right. Good job and good luck
GoldRush18
  • GoldRush18
omg thank u so much, im understanding so much better now
anonymous
  • anonymous
What are your other questions?
GoldRush18
  • GoldRush18
do u have an email address, its in a word document
anonymous
  • anonymous
wow that assignment is awful
GoldRush18
  • GoldRush18
i know right, and its like we have to research it because they haven't though us as yet
