Answer:
=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
