Question

Today only, a suit is being sold at a 15% discount. The sale price is $391.

What was the price yesterday?

Answer 1

$460.

Explanation:

`Percentage\ change = ((Original\ Price\ - Discounted\ Price)/(Original\ Price))100\\\\15=((x-391)/(x))100\\\\15x=(x-391)100 \\\\15x/100=x-391\\0.15x=x-391\\391=x-0.15x\\391=0.85x\\391/0.85=x\\460=x\\`

So the price yesterday was $460
