Eben figures he can work a part-time job for 20 hours a week, 50 weeks a year, for the next four years to earn money for his higher education. He wants to pursue a two-year program at a community college and figures he will need $22,500 each year for tuition, fees, and living expenses. What is the minimum he must make per hour?
First, we need to calculate the total cost of Eben's education for two years. Since he needs $22,500 each year, the total cost will be $22,500 x 2 = $<<22500*2=45000>>45,000.
Next, we need to calculate the total number of hours Eben will be working over the next four years. Since he plans to work 20 hours/week x 50 weeks/year = 1000 hours/year.
Therefore, he will work a total of 1000 hours/year x 4 years = <<1000*4=4000>>4000 hours.
Finally, we can calculate the minimum hourly wage Eben must make by dividing the total cost of his education by the total number of hours worked. $45,000 รท 4000 hours = $<<45000/4000=11.25>>11.25 per hour. Answer: \boxed{11.25}.
