Question

Juan buys a book on sale for 30% off its retail price. He pays $14.70 for the book. What is the retail price of the book?

Answer 1

$14.70×30%= 14.70×30/100 = 441/100 = 4.41
$14.70 + $4.41 = $19.11

Answer 2

30 percent off is equal to 70 percent of the price

retail price * 70 percent = 14.70

retail price * .70 = 14.70

divide by .70

retail price = 14.70/.70

retail price = 21.00
