Shirts are on sale for 30% off. the original price of one shirt is $15. what is the total cost, in dollars, of 2 of these shirts at the sale price, including a 7% sales tax? enter your answer in the space provided.

 =22.47

Step-by-step explanation:

We are buying 2 shirts

Before discount  2*15 = 30

We get 30% off.  That means we pay 70 percent of the price

$30 * 70% =

30 *.7

21

The cost of the shirts before tax is 21 dollars

Tax is the cost of the shirts after discount  times the tax rate

tax = 21 * 7%

tax = 21 *.07

tax =1.47

We add the tax to the cost of the shirts

Final cost = discount price + tax

                =21+1.47

                =22.47
