They charge $2.50 for a bag of popcorn and $2 for a pretzel. The parents collect $336 in sales during the game. They sell twice as many bags of popcorn as pretzels. How many bags of popcorn do they sell? How many pretzels do they sell?
Answer provided by our tutors
let
c = the number of popcorn bags sold
p = the number of pretzels sold
the parents collect $336 in sales during the game
2.50c + 2p = 336
they sell twice as many bags of popcorn as pretzels.
c = 2p
by solving the system of equations
2.50c + 2p = 336
c = 2p
we find
c = 96 popcorn bags
p = 48 pretzels
