Jose has had his eye on a pair of basketball shoes at a shoe store for a long time, but at a price of $150, the shoes have always been a little bit more than his budget could handle. however, today he saw a sign in the window that said, "basketball shoes – 20% off." which type of discount is this?

a. a sale
b. a coupon
c. a rebate
d. a gift card

This type of a discount is:

       A.   A sale

Sale--

A sale is a transaction between two parties one is a buyer and other is seller in which the goods or services are provided by the seller at a lower rate as compared to the normal price of it.

The price so lowered is known as a discounted price and the price at which the item is to be sold is known as a sale price.

Here the store is keeping the basketball shoes at a sale which is displayed on window as:

      "Basketball Shoes – 20% off."

            Hence, the correct option is: Option: A

                                A. A sale
