Question

A hotel room that is advertised at $120 per night. You notice in the fine print that there will be an additional 18% tax on the room. How much tax will you pay? How much will you actually be charged per night, including the tax?

Answer 1

The tax and the total per night is calculated with $120 * 118%. You then will get $120*1.18, which is, $141.6. To get the tax alone, you can multiply $120 to 18%, and get $21.6.

Remember that percentages are basically a fraction over 100. (Ex. 18% is 18/100. You can simplify it to 0.18)

It will cost $21.6 in tax each night alone, but will cost $141.6 in total.
