Question

A city has a 5% sales tax. A book costs $32.55 after tax. How much did it cost before tax?

Answer 1

$31

Explanation:

Let's assume the cost of the book before tax is represented by "x"

5% = 0.05

We have:

x + 0.05x = 32.55

1.05x = 32.55

Divided both sides by 1.05

x = $31

So, the book costs $31 before tax.
