Don't tell me how much money you have; I do not wish to be nosy, but I bet I can figure it out! It’s fun.

First of all, count how much money you have in your wallet. If you have small change, round to the nearest dollar (if you have 55.15 dollars, then just round to 55 dollars.)
Multiply this number by 2 (just to be bold)
Add 3 to the result
Multiply by 5 (if needed, use a calculator to figure out)
Subtract 6 from what you get

You will end up with a number that ends in the digit 9. Remove this digit and keep the remaining number (ex. 459 —> 45)

The rest of the numbers will equal THE MONEY IN YOUR WALLET!

Example of the process:
