Question

Tommy buys a sweater that is on sale for 40% off the original price. The expression p -0.4p can be used to find the sale price of the sweater, where p is the original price of the sweater. If the original price of the sweater is 50, what is the sale price?

Answer 1

The way to find this answer is to multiply 50 by .4, and this equals 20. Now, subtract 20 from 50. The sale price is 30.
