Dave works at a mall part-time for $9 per hour and notices that 20% of his check is deducted for taxes. If he wants to take home at least $200 per week, how many hours does he have to work?

Answer: 28 hours

Solve it using a system of linear equations, showing details of how you set up your equations and the steps that you went through for the solution.

Use Polya's Four-Step Method for your analysis. If you need assistance, please ask for assistance from me or from one of your fellow students. The problem must be solved using one of our accepted methods - substitution, elimination or graphically.

Any help please.
