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
