Answer

Explanation:

Step1: Find the pre - tax price

Let the pre - tax price be $x$. We know that $8%$ of $x$ is $10.50$, so $0.08x = 10.50$. Solving for $x$, we get $x=\frac{10.50}{0.08}=131.25$.

Step2: Calculate the total cost

The total cost is the pre - tax price plus the sales tax. So the total cost $C=x + 10.50$. Substituting $x = 131.25$ into the equation, we get $C=131.25+10.50 = 141.75$.

Answer:

D. $141.75$
