Answer:

$129

Step-by-step explanation:

80 + 2(20) = 80 + 40 = 120

With tax: 100 + 7.5 = 107.5%

107.5/100 × 120

129

Answer:

129

Step-by-step explanation:

First find the cost for how much was purchased

boots: 80

2 shirts: 2*20 = 40

80+40 = 120

The tax is the cost times the tax rate

tax = 120 * 7.5%

      = 120 * .075

       9

The total cost is the cot plus the tax

total cost = 120+9

                 =129
