The shoe store is having a sale. All items are 30% off the regular price, and the store will pay 1/2 of the sales tax. Sales tax is 8%. How much would you pay for pair of shoes, if the regular price is $50.00?

First, you need to find 30% of 50. To do so, you have to turn 30% into a decimal by dividing 30 by 100.

30% ⇒ 0.3

Now, find 30% of 50 by multiplying 50 by 0.3.

50 × 0.3 = 15

30% of 50 is 15, so the discounted price of the shoes would be $15.00.

We aren't done yet though! We still need to factor in the tax. 1/2 of the sales tax, 8%, is 4%. Find 4% of 15 using the same process as before.

4% ⇒ 0.04

Multiply.

0.04 × 15 = 0.60

Add 0.60 to 15.

0.60 + 15 = 15.60

You would pay $15.60 for a pair of shoes with a regular price of $50.00.
