To get the the cost of how much Alexis is paying we first have to find the original cost and then subtract the $15 which is equal to 20% of the original number.
To find the original price you take the $15 and divide it by .20
15÷.20= 75
To get the original price of a percentage you do the opposite of if you were trying to find the % for example :
75 x .20 = 15
15 ÷ .20 =75
The original price is $75
75 - 15 = 60
With the discount it is $60
