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

12 cups

Step-by-step explanation:

If the size of the bag decreased by 20%, so will the number of cups held.

Number of cups held before the change = 15 cups

If the number of cups held after the 20% reduction in the size of the bag

= (100 - 20) % * 15

=80% * 15

= 12 cups

The new bags will hold 12 cups.
