Answer:
Step-by-step explanation: the discount on the original price is a 20% discount, so it is 20% of x, or 0.2x.
We are told the discount is $3, so 0.2x = 3. Now we solve the equation for x.
0.2x = 3
Divide both sides by 0.2.
x = 3/0.2
x = 15
The regular price is $15.
Answer:
12
Step-by-step explanation:
x = original price
x* 20% = 3
Change to decimal form
x*.2 = 3
Divide each side by .2
x*.2 /.2 = 3/.2
x =15
The original price is 15
Selling price is 15-3 = 12
