Question

A retailer returned 300 defective items to the manufacturer and received a credit for the retail price of $0.75 less a discount of 1/3 of the retail price. What was the amount of the credit received by the retailer?

Answer 1

so he received  $0.75 - 1/3*$0.75 = $0.50 each

300 defective items so:

300*$0.50 = $150
