Explanation:

Step1: Calculate the discounted price

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

Step2: Calculate the price after sales - tax

The sales - tax is $4.5\%$ on the discounted price. The price after tax is $70.55\times(1 + 4.5\%)=70.55\times1.045=73.72475$.

Step3: Calculate the total purchase price

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

Answer:

A. $80.07$
