A discount of 18% on a tennis racquet reduced its price by $16.91. What was the sale price?

OpenStudy (anonymous):

set x = original price.

OpenStudy (anonymous):

so, (reduced price) = (original price) - (rate of discount written in decimal form)*(original price).

OpenStudy (anonymous):

note, on writing the rate in decimal form, move the decimal point two units to the left, example: 12% will be 0.12.
