Question

What is total cost of three pairs of socks priced at 1.29 a pair, with a 6% sales tax?

Answer 1

$4.10

Explanation:

Subtotal = (3 pairs of socks) x (price of socks):

Subtotal = (3 x $1.29) = $3.87

To get the overall total, you add tax, which is 6% of the subtotal:

6% of the subtotal = 0.06 x subtotal = 0.06 x $3.87 = $0.23

Subtotal + tax = $3.87 + $0.23 = $4.10
