Question

Erica saw a sweater on sale for $39.95. The original price of the sweater was $59.95. What is the approximate percent of discount on the sweater?

1. 
   

Answer 1

(59.95-39.95)/59.95 = 20/59,95

= about 20/60=2/6=1/3

= about 33% off

= about 1/3 off

or more precisely about 33.3611342%
