A sporting good store is offering an additional 30% off all clearance items and she purchases a pair of running shoes on clearance for $65 if the shoes originally cost $85 what was her total discount?

Total discount = $39.50

or 46.47 %

Step-by-step explanation:

First we need to figure out what she will pay for the shoes. She is getting 30 percent off the 65 dollars.

Discount = price * percent off

= 65*.3

= 19.50

The cost of her shoes is the price minus the discount.

Cost = 65 - 19.5

= 45.50

To find the total discount, take the original price and subtract the final cost.

Total discount = 85-45.50

= 39.50

To find the total percent discount, we use the formula

total percent discount = (original - final) / original * 100

= (85 - 45.50) / 85 * 100

= 39.5/85*100

= 46.47%
