Answer:
The percentage saved is 1.5% .
Explanation:
As given
You plan to buy $12,000 in computers at a local chain store. There are two stores located about the same distance from your office but in different cities with different tax rates.
One city has a tax rate of 7% and the other has a tax rate of 8.5%.
As
7% is written in the decimal form .

= 0.07
Tax price at 7% tax rate = 0.07 × Cost of the computer
= 0.07 × 12000
= $ 840
8.5% is written in the decimal form .

= 0.085
Tax price with 8.5% tax rate = 0.085 × Cost of the computer
= 0.085 × 12000
= 1020
Change in the tax rate = Tax price with 8.5% tax rate - Tax price at 7% tax rate.
= 1020 - 840
= $180



Percentage saved = 1.5%
Therefore the percentage saved is 1.5% .
