About 35 Hours, 35.0140056 to be exact.
1. I wrote out the word problem to have Maria’s pay hourly, then the percentage of tax from that pay, and finally the 25$ after taxes they pay.
2. I went ahead and deducted the percentage of taxes, 25%, from the hourly pay to see how much Maria really takes home.
2.5. I subtracted the tax amount, 1.19$, from Maria’s hourly pay to show how much they take home.
3. I wrote out an equation of the amount Maria takes home multiplied by the hours they work, X, and minus the 25, to finally equal the amount Maria wants to take home. Solved the equation.
4. X is the amount of hours Maria has to work to take home 100 dollars with tax and the union fee.
I hope this is correct!! And that it helped!! :)
