A magazine costs $4.50 with 7% tax. What is the total bill including tax?

4.82

Step-by-step explanation:

First you do: 4.50 times 7%

To make it easier, you do 7% into a decimal, which is 0.07

Then, you do 4.50 times 0.07, and get 0.315

Lastly, you want to do 4.50 plus 0.315 and get: 4.815

If you want to convert it into the money state, you get $4.82.
