The T-Shirt Order
Derek receives an order to produce 120 custom t-shirts in 4 days. Working alone, he can print 18 shirts per day. To meet the deadline, he hires his friend Jenny, who can print 12 shirts per day working an 8-hour shift and charges $15 per hour.
How much will Derek have to pay Jenny to help complete the order on time?
Solution
18 x 4 = 72 12 x 4 = 48 Derek can print 72 t-shirts in 4 days Jenny can print 48 t-shirts in 4 days That would total to 120 t-shirts in 4 days In order to complete the order, Derek must hire Jenny for 4 days
To calculate Jenny's payment: 8 hours/day x 4 days = 32 hours 32 hours x $15 / hour = $480 Derek has to pay Jenny $480 to help complete the order. |
