2. ### how to make OVER TIME go back to wages http://consumermath.org/wp-content/uploads/PF-Practice-4.2-Calculate-Wage-Rate-Sheet-A.pdf?

I don't know where you live, but generally "overtime" is 1.5 x ordinary time and "double time" is 2 x ordinary time, as it suggests. So to convert either back into ordinary rates, you divide by 1.5 or by 2. e.g. Number 7, overtime is \$16.05, so ordinary time...
