Kristin wants to buy a pair of jeans that cost $35 and are on sale 20% off. She is also buying two T-shirts at a full price of $9.99 each.
She must pay 6.5% sales tax. How much will she pay for the clothes

$51.10

Step-by-step explanation:

First, find 20% of $35, then add the sale price of the jeans and the two t-shirts. Take the total and find the sales tax and add that onto the cost.

100 - 20 = 80 If you multiply the jeans by 80% it gives you the price for the jeans saving you from having to subtract the discount from the original price.

35 * 0.80 =  $28.00 jeans                     28.00                             47.98

                                                                  9.99                             + 3.12

                                                             +   9.99                            $51.10

                                                                47.98

                                                           X   0.065

                                                                 $3.12
