Act problem: the community orchestra will give 18 performances this season. A season ticket cost $60 each, and a single performance cost $ 5 each. Huong purchased a season ticket. What is the minimum number of performances Huong must attend to save money by buying the season ticket instead of buying single performance tickets for the performances she already attended?

so you need to solve
5x = 60
for x
to find when he will spend $60 on buying single tickets only

- jim_thompson5910

tell me what you get

- anonymous

So it would be 12?

- jim_thompson5910

good, so the minimum is 13 because buying 13 single tickets will cost 13*5 = 65 dollars
compare this with a season pass which only costs $60
so you're saving $5 if you buy a season pass (and you go to 13 concerts)

- jim_thompson5910

make sense?

- anonymous

Wait but would'nt 12 be the answer then? and isnt 12 the minimum not 13?

- jim_thompson5910

12 is when the two prices are equal

- jim_thompson5910

the answer isn't 12 because you could buy a season pass or 12 individual tickets and it wouldnt' matter

- jim_thompson5910

13 is when you start saving money with the season pass

- anonymous

so then the answer is 13 is how many performances she would be able to see with the season ticket instead of the singl performance ticket right?

- jim_thompson5910

exactly

- jim_thompson5910

that's the point where you would choose a season pass over a single ticket

- anonymous

and 12 would be a distractor because a student like me would just divide 5 by 60 to find the # of tickets but the amount of performances he might see with the season ticket right?

- jim_thompson5910

12 is where the two are equal, so buying either one won't save you money

- jim_thompson5910

which is why you bump it up from 12 to 13

- anonymous

Do you know any possible answers a student might get if he did it a wrong way? i already got 2 of the answers i just need 2 more possible distractors though

- jim_thompson5910

hmm not sure what you mean by this

- jim_thompson5910

like just two more wrong answers?

- jim_thompson5910

usually you try to get to the answer, not the wrong answer lol

- anonymous

lol true but yeah i need 2 more wrong answers>.<

- jim_thompson5910

hmm well just anything below 13 will work (as a wrong answer)
example:
10*5 = 50 which is less than 60, so the individual tickets are still cheaper if you just go to 10 concerts

- jim_thompson5910

or if you go to 9 concerts, then 9*5 = 45 , which is also less than 60
so it's still cheaper to buy individual tickets

- anonymous

wait so is 13 the right answer then? cause the question is what is the minimum numbr of performscs the person must attend to save $ by using the season ticket instad of buying single performance tickets for the permances she attends/

- jim_thompson5910

yes 13 is the min

- jim_thompson5910

13 or above is where you start saving

- anonymous

lol you're gona kill me>.< i need one last wrong answer lol

- jim_thompson5910

lol anything below 13 works, so 9, 10, or 11 works as a wrong answer

- anonymous

lol thank you very much! ^-^

- jim_thompson5910

you're welcome
