The movie house give away a $5 coupon for every 4 movies purchased. they give away a bag of popcorn for every 3 movies purchased. how many movies will a person need to purchase before receiving a both a $5 coupon and a bag of popcorn at the same time?

12 movies

if they receive a coupon for every four movies, and a bag of popcorn for every three movies, you need to find the LCM (lowest common multiple) of the two numbers, which is 12.

good luck!

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
