Question

A city has a 5% sales tax.

A toothbrush costs $3.40 before tax.
How much does it cost including tax?

Answer 1

Answer: $3.57

Explanation:

1.) When converted to a decimal,

5% = 0.05

It can also be seen as 5/100. 5 out of 100.

2.) Next, multiply 0.05 by 3.40

(0.05)(3.40) = 0.17

0.17 is the 5% tax that was added onto the original price (3.40)

To get the total price, add 3.40 and 0.17.

Your answer is: $3.57
