PRE ALGEBRA AND SALE TAX

Question

Gabriela bought a new pair of glasses at the store when they were having a 30% off sale.

If the regular price of the pair of glasses was $72, how much did Gabriela pay with the discount?

Answer 1

discount price = (1-.30)72 = .7(72) = $50.40

30% off means paying 70% of the regular price
