Question

The Hudson Record Store is having a going-out-of-business sale. CDs normally sell for $18.00. During the first week of the sale, all CDs will sell for $15.00. Written as a fraction, what is the rate of discount? What is this rate expressed as a percent? Round your answer to the nearest hundredth of a percent. During the second week of the sale, the same CDs will be on sale for 25% off the original price. What is the price of a CD during the second week of the sale?

Answer 1

The normal cost of CDs = $18

During sale, the cost of CDs = $15

So,

The discount = 18 - 15 = 3

The discount as fraction = 3/18 = 1/6

The discount as a percent = (1/6) * 100% = 16.67% (rounding to the nearest hundredth)

===========================================================================

During the second week, CDs will be on a sale of 25% off the original price

so, the discount = 25% of 18 = (25/100) * 18 = 4.5

so, the price of a CD during the ssecond week = 18 - 4.5 = $13.5
