Question

sara bought a new doll at a 20% off sale and saved $12. What was the regular price of the doll?

Answer 1

Answer:

regular price = $15

Step-by-step explanation:

Represent the regular price by d.  Then the discount was 0.20d, and the sale price was (1 - 0.20)d, or 0.80d, which is $12.

Solving for d, we divide both sides by 0.80:

d = regular price = $15
