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

At your hardware store, you buy hammers for \$30 a dozen and sell them for \$3.50 each. What is the percent markup for the hammers?
