Question

A tennis racket normally costs $80. The tennis racket is on sale for 30% off. What is the sale price of the tennis racket

Answer 1

The answer would be $56
The reason is you would do 80*.3(30% in decimal form) which would equal 24
24 is what is being taken off of the normal cost.
So you would then do 80-24 which would equal $56.
