A new backpack costs $45.00 plus 7.4% for sales tax. Find the amount of tax you would have to pat for the backpack.

$48.33

Step-by-step explanation:

1. Find the amount of the sales tax by multiplying the tax percentage by the sales price.

$45 × 7.4% = $3.33

2. Add the amount of the sales tax back to the sales price.

$45.00+$3.33 = $48.33
