Question

If you are buying at item at a store for a price of $13, and there is a 5.6% tax added on top, what would be the total amount due at the register, to the nearest cent?

Answer 1

The total would be $13.73

Explanation:

Convert percent to a decimal: 5.6% =
`(5.6)/(100)` =0.056

Percent formula: a(1+r)

13(1+0.056)

13(1.056)

13.728

and then if you round that to the nearest cent it would be 13.73

Answer 2

$13.73 with tax

tax is 0.73 cents

Explanation:

We simply just multiply 13 by 5.6 and get 0.728. Since we are rounding to the nearest CENT we get 0.73!
