Answer

Explanation:

Step1: Calculate cost at store A

First, find the price after tax: $1000\times(1 + 0.05)=1000\times1.05 = 1050$. Then subtract the rebate: $1050-80 = 970$.

Step2: Calculate cost at store B

Find the price after discount: $1000\times(1 - 0.1)=1000\times0.9 = 900$. Then find the price after tax: $900\times(1 + 0.05)=900\times1.05=945$.

Step3: Calculate cost at store C

The store pays the tax, so the cost is just the retail - price: $1000$.

Step4: Calculate cost at store D

First, find the price after tax: $1000\times(1 + 0.05)=1050$. The store pays half of the tax, so the tax paid by the customer is $1000\times0.05\times\frac{1}{2}=25$. Then subtract the rebate: $1000 + 25-40=985$.
