Need helpp!! Robert spends $30.45 before tax at the bookstore. If the sales tax rate in his city is 7.25%, what is the total cost of his purchase?

$32.65 is the answer.

Step-by-step explanation:

First, we must calculate 7.25% of 30.45.

30.45 x 0.0725 = $2.20

Now, we must add this to the original price

$30.45 + $2.20 = $32.65

Therefore, $32.65 is the total cost of his purchase.

Hope this helps! :)

Step-by-step explanation:

before tax = $30.45

tax sales = 7.25%

total cost = $30.45 x 1.0725

               = $32.66
