A pair of shoes costs $40 and there was a $20 off sale. Sales tax is 8%. How much is the total cost?

To calculate the total cost of the shoes, we need to consider the discount and the sales tax.

First, we apply the discount of $20 to the original price of $40:

Discounted Price:

$40 – $20 = $20

Next, we need to calculate the sales tax on the discounted price. The sales tax is 8% of the discounted price ($20):

Sales Tax:

8% of $20 = 0.08 * $20 = $1.60

Now we can find the total cost by adding the discounted price and the sales tax:

Total Cost:

$20 + $1.60 = $21.60

Therefore, the total cost of the shoes after the discount and including sales tax is $21.60.
