William is planning to buy a guitar for $35.95. The sales tax rate is 8.25%. He wants to be sure he has enough money. How much will the guitar cost, including sales tax?

If you would like to know how much will the guitar cost, including the sales tax, you can calculate this using the following steps:

8.25% of $35.95 = 8.25% * 35.95 = 8.25/100 * 35.95 = $2.97

$35.95 + $2.97 = $38.92

The correct result would be $38.92.
