Question

You need to buy 18 rolls of film. One shop sells it for$9.95 plus 5% sales tax. Another shop $9.75 per roll and charge $15.00 to ship no sales tax. Choose the better of the two prices how much will you pay for 18 rolls of film?

Answer 1

We will buy it at $9.95 plus 5% tax because it is slightly cheaper than other price

Explanation:

$9.95 x 18 = 179.10 + 5% sales tax(8.95) = 188.055

$9.75 x 18 = 175.50 + 15 = 190.50

hence sales tax can be get back by submitting monthly return file. so the first method is cheaper than second one,
