Owner buys coats for $60.00/ea

Owner sells coats for $72.00/ea

a. What percent of the purchase (60.00) is the sale price (72.00)?

60/72 = 83.33
(multiply by 100 to get percentage)

The purchase price is 83.33% of the sale price.

b. The sale price (72.00) is ___ % of the purchase price (60.00)

72/60 = 1.20
(multiply by 100 to get percentage)

The sale price is 120% of the purchase price.

20%

First we calculate the difference between the purchase and sale price.

$72.00 - $60.00 = $12.00

$12 is the increase in dollars. In order to increase as a percentage it is now necessary to divide the increase by the original purchase price.

12.00 ÷ 60.00 = 0.2

To get the final percentage we multiply the answer by 100. This simply means moving the decimal place two columns to the right.

0.2 x 100 = 20

Therefore the percent of the purchase price is 20% of the sale price.
