Question: Janet makes $20 per hour at work. She works 52 hours per week. Anything over 40 hours per week is considered overtime and is paid at 1.5 times the normal rate. She wants to purchase a $4640 car. How many weeks does she need to work to purchase the car? Think carefully first, then make a decision:
Each week she makes $20 * 40 = $800 from her normal hours. For overtime she makes $20 * 1.5 = $30 per hour. Each week she works 52 - 40 = 12 overtime hours per week. She makes a total of 12 * $30 = $360 from overtime every week. This means she makes a total of $800 + $360 = $1160 per week. To reach $4640 she would need to work $4640 / $1160 = 4 weeks. So the answer is 4.
