What is the discount if you pay $6.00 from $15.00

40%

Step-by-step explanation:

You would divide because to find a percent, you can use a equation. Like

A=PW

A = Part = $6

P = Percent = x (unknown)

W = Whole = $15

Equation = 6 = 15x.

To figure out x you have to isolate it so you would divide because the inverse operation of multiply is divide and you have to divide 15 on both side. 6 divided by 15 is 0.4. 0.4 is equal to 40%
