Question

A pack of cinnamon-scented pencils sells for $6.00. What is the sales tax rate if the total cost of the pencils is $6.42?

Please show how you did it

Answer 1

Cross multiply
.42/6 = x/100%

.42 * 100% = 42
42/6 = x = 7%

Answer 2

7% sales tax

Explanation:

If the pencils cost $6, then the sales tax costs $6.42 - $6 = $0.42. To find the rate, we must divide $0.42 by $6. $0.42/$6 = 0.07. 0.07 is 7%.
