Question

A movie theater decreased the size of its popcorn bags by 20%. If the new bags hold 12 cups of popcorn, how much did the original bags hold? Nasser used the equation 0.20x = 12 Abraham used the equation 0.80x = 12 Kathleen used the equation 1.20x = 12 Decide who used the correct equation and defend your reasoning.

Answer 1

nasser

Explanation:

0.20 = 20/100=20%

Answer 2

Abraham

Explanation:

Abraham used the correct equation because if we represent the original size as 100% and decrease that by 20 it would be 80% or 0.8

Nasser's equation will solve for the change in price

Kathleen's equation solves for if the popcorn size was increased by 20%
