Answer

Explanation:

Step1: Calculate the discounted price

The original price is $83. The discount is 15%, so the price after discount is (83\times(1 - 0.15)=83\times0.85 = 70.55) dollars.

Step2: Calculate the price after sales - tax

The sales - tax rate is 4.5%. The price after tax is (70.55\times(1 + 0.045)=70.55\times1.045=73.72475) dollars.

Step3: Calculate the total cost

Add the shipping fee of $6.35 to the price after tax. The total cost is (73.72475+6.35 = 80.07475\approx80.07) dollars.

Answer:

A. $80.07
