A backpack that normally sells for $39 Is on sale for 33% off. Find the amount of the discount and the sale price
Nataliya [291]
To get the price, you have to multiply the amount by the percent it would become.

100% of 39 is 39
It is 33% off
100 (1.00) - 33 (0.33) = 67% (0.67)

Remember, the percent is a decimal because it is part of a whole (1).

39*0.67=$26.13.
