Question

ales tax is calculated as a percentage of the sales price. If sales tax is 7%, what is the sales tax on clothing that costs $150

Answer 1

7% of 150= 10.5 :)

Explanation:

150/x=100/7

(150/x)*x=(100/7)*x - we multiply both sides of the equation by x

150=14.2857142857*x - we divide both sides of the equation by (14.2857142857) to get x

150/14.2857142857=x

10.5=x

x=10.5

now we have:

7% of 150=10.5
