Answer

Answer:

B. The total cost of the desk including sales tax will be higher at store A by about $9.

Explanation:

Step1: Calculate total cost for store A

The sales - tax amount for store A is $289.99\times0.07=$20.2993$. The total cost at store A is $289.99 + 20.2993=$310.2893$.

Step2: Calculate total cost for store B

The sales - tax amount for store B is $299.99\times0.065=$19.49935$. The total cost at store B is $299.99+19.49935 = $319.48935$.

Step3: Find the difference

The difference in total costs is $319.48935 - 310.2893=$9.20005\approx$9$. Since $319.48935>310.2893$, the total cost is higher at store A by about $9$.
