The running shoes Gina bought at a 20%-off sale were originally priced at $70. Before tax was added, how much money did Gina save by buying the shoes on sale?
70*0.20 = $14
To find out how much money Gina saved by buying the shoes on sale, we need to calculate the amount of discount she received. The discount is calculated as a percentage of the original price. In this case, the discount is 20% of the original price of $70.
To calculate the discount amount, we multiply the original price by the discount percentage. In this case, we have:
Discount amount = Original price * Discount percentage
= $70 * 20%
= $70 * (20/100)
= $70 * 0.20
= $14
Therefore, Gina saved $14 by buying the shoes on sale.
