108. Figure 13-4.Connolly Company produces two types of lamps, classic and fancy, with unit contribution margins of $13 and $21, respectively. Each lamp must spend time on a special machine. The firm owns four machines that together provide 18,000 hours of machine time per year. The classic lamp requires 0.20 hours of machine time, the fancylamp requires 0.50 hours of machine time.Refer to Figure 13-4. What is the contribution margin per hour of machine time for a classic lamp?
A. $26B. $104C. $16D. $65E. $13

112. Figure 13-5.Santorino Company produces two models of a component, Model K-3 and Model P-4. The unit contribution margin for Model K-3 is $6; the unit contribution margin for Model P-4 is $14. Each model must spend time on a special machine. The firm owns two machines that together provide 4,000 hours of machine time per year. Model K-3 requires 15 minutes of machine time; Model P-4 requires 30 minutes of machine time.Refer to Figure 13-5. What is the amount of machine time for model K-3 in terms of percent of a machine hour?
A. 10%B. 20%C. 25%D. 40%E. 50%
