Sara buys a book for $17.50 and a pen for $6.50. If the sales tax rate is 8.25%, what will be the total amount of sales tax on h
Nuetrik [128]

Answer:

$25.98

Step-by-step explanation:

Add the items Sara buys to find the total:

17.50 + 6.50 = 24

Convert 8.25% into a decimal:

8.25/100 = 0.0825

Multiply 0.0825 by 24:

0.0825 x 24 = 1.98

1.98 is the amount of tax, then add the tax to the total amount you got before tax.

24 + 1.98 = 25.98

Your answer would be 25 dollars and 98 cents!
