Question

1. a movie theater decreased the size of its popcorn bags by 20%. if the old bags held 15 cups of popcorn, how much do the new bags hold?

Explanation:

Step1: Find the percentage of the new size

The size is decreased by 20%, so the new size is \(100\% - 20\% = 80\%\) of the old size. In decimal form, \(80\% = 0.8\).

Step2: Calculate the new capacity

Multiply the old capacity (15 cups) by the decimal representing the new size. So, \(15\times0.8 = 12\).

Answer:

The new bags hold 12 cups of popcorn.
