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?

Step-by-step explanation:

since this is a percent deal I would a simple trick

x/15 = 20/100

15 x 20 = 300

divide 300 by 100

that equals 3

15 - 3 = 12

in mathematics, a function is a relationship between two variables such that the value of one of the variables, called the dependent variable, is determined by the value of the other variable, called the independent variable. there is a specific term we use to describe the set of independent variables of a function.

the least value out of the data shown is 5, maybe if you post a picture with it i could a little more.
