Answer
Answer:
C. store C
Explanation:
Step1: Calculate total cost at store A
First, find the sales - tax amount: $1000\times0.05 = 50$. Then the total cost is $1000 + 50-80=970$.
Step2: Calculate total cost at store B
The discounted price is $1000\times(1 - 0.1)=900$. The sales - tax amount is $900\times0.05 = 45$. So the total cost is $900+45 = 945$.
Step3: Calculate total cost at store C
The store pays the sales tax. So the total cost is just the retail price, which is $1000$.
Step4: Calculate total cost at store D
The sales - tax amount is $1000\times0.05 = 50$. The store pays half, so the customer pays $50\div2 = 25$. With a $40$ rebate, the total cost is $1000+25 - 40=985$. Since $945$ (store B) is the lowest cost among all the options, store B has the best deal.
