Answer

Answer:

C. store C

Explanation:

Step1: Calculate price at store A

First, find the total cost before rebate: $800\times(1 + 0.05)=800\times1.05 = 840$. Then subtract the rebate: $840-75 = 765$.

Step2: Calculate price at store B

Find the price after 10% off: $800\times(1 - 0.10)=800\times0.90 = 720$. Then add sales - tax: $720\times(1 + 0.05)=720\times1.05=756$.

Step3: Calculate price at store C

Find the price after 5% off: $800\times(1 - 0.05)=800\times0.95 = 760$. Since the store pays the sales - tax, the final price is $760$.

Step4: Calculate price at store D

The price without tax is $800$. Then add the tax amount that the store pays: $800\times(1 + 0.05)=840$.

Comparing the prices: $756<760<765<840$. Store B has the lowest price, so store C has the best deal among the given options.
