A shop owner offered a 40% discount off the regular price of a mirror. The amount of the discount is $6. What is the regular price of the mirror?

Step-by-step explanation:

the original price of the mirror is not known so we will call it x for now.

The discount on the original price is a 40% discount, so it is 40% of x or 0.4x

We are told that the discount is $6, so 0.2x will = 6. So now we will solve the equation for x.

0.4x = 6

x= 6/0.4

x= 15

The original price is $15
