store a charges $1,200 for repairs with a 6 percent sales tax. store b charges $1,350 with a 7 percent sales tax. explain how you would determine the amount of money saved by using store a instead of store b?

Answer

Explanation:

Step1: Calculate total cost of Store A

First, find the sales - tax amount for Store A. The sales - tax rate is 6% or 0.06. The tax amount is $1200\times0.06 = 72$. Then the total cost of Store A is $1200 + 72=1272$.

Step2: Calculate total cost of Store B

The sales - tax rate for Store B is 7% or 0.07. The tax amount is $1350\times0.07 = 94.5$. Then the total cost of Store B is $1350+94.5 = 1444.5$.

Step3: Calculate money saved

Subtract the total cost of Store A from the total cost of Store B. The money saved is $1444.5−1272 = 172.5$.

Answer:

First, calculate the total cost of repairs at each store by adding the repair cost and the sales - tax amount (repair cost×sales - tax rate). Then subtract the total cost of Store A from the total cost of Store B. The money saved is $172.5$.
