A women went to the store to purchase shoes during a "30% off" end-of summer discount sale.
A. After the discount the price of one pair of shoes is $15.40. What was the price of the shoes before the discount
let the price of the shoes before the discount be x

x=%2830%2F100%29x+%2B15.40

x=%280.30%29x+%2B15.40
x-%280.30%29x+=15.40
0.7x+=15.40
x+=15.40%2F0.70
x+=22.....your answer: the price of the shoes before the discount

the discount was %2830%2F100%29x+=%2830%2F100%2922+=+0.3%2A22=6.60 dollars
