You plan to attend night school in 3 months so you can qualify for a promotion at work. You need to earn an additional $1,140 for tuition within that time. You take a second job, which pays $8 per hour. The work schedule is flexible, and you can work as many hours as you want. Taxes take 15% of your wages and you save the rest. Over the next 3 months, what is the minimum number of hours you could work each month to earn the money for tuition?
Due to the taxes yo must pay (15%) , $ 1,140 represents 85% of what you must save.
100% would be 1341.18 at $8/hr this is 1341.18/8 = 167.65 hours
ASSUMING 4 weeks in a month you have 4wks/mo x 3 mo = 12 weeks to work this many hours
167.65 hrs/12weeks = 13.97 ~~ 14 hrs/week
