Answer:

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.

The old bags held 15 cups of popcorn so, the new bags holds 12 cups of popcorn and this can be determined by using the unitary method.

Given :

  • At a movie theater, the size of popcorn bags decreased 20%.
  • The old bags held 15 cups of popcorn.

The unitary method can be used to determine the total number of cups of popcorn the new bag can hold.

Given that the old bags held 15 cups of popcorn, so, it is 100% capacity of the old bag. So, according to this capacity, the new bag can 80% of cups of popcorns that is:

[tex]=\dfrac{80}{100}\times 15[/tex]

Multiply 80 by 15 in the above expression.

[tex]=\dfrac{1200}{100}[/tex]

Now, divide 1200 by 100 in the above expression.

= 12 cups of popcorn
