Question

Mike earns an hourly wage at the cell phone store. The following expression represents Mike's take home pay after taxes, social security, and health care plan are deducted and x represents the number of hours Mike worked.

15.20x-0.18(15.20x)

Mike wants to save $500. If Mike saves 50% of his take home pay, how many hours will he need to work to meet his savings goal?

Answer 1

15.2x - 18% of x = 82% of 15.2 = 12.464 as take home pay per hour

saving half is 6.232

500/6.232 = 80.2 hours to save $500
