Question

A new cell phone costs $85, and the sales tax is 9%. What is the amount of the sales tax?

Answer 1

Sales tax = `$7.65`

Explanation:

To find the sales tax, you would find `9%` of `$85`

`$85*9/100` (You can reduce 85 and 100 because they have a common factor of 5)

`$17*9/20` (Multiply `9*17`)

`153/20` = `$7.65`
