Answer:
$200
Explanation:
She paid 85% of the original price (since it was discounted 15%)
So
187 = 0.85x (where x is the original price, and 0.85 is 85% as a decimal)
This reads as "187 is 85% of some value". In this case, the value is the original price we are looking for. Solve this equation to find x
187 = 0.85x
220 = x (divide both sides by 0.85 to isolate x)
