Answer:
The largest possible total contribution margin that can be realized each period is that of product C ($840,000).
Explanation:
Product L has a contribution margin of $120 but it requires 10 minutes per unit. Therefore, 120/10 = 12. This means its contribution margin is $12.
Product C has a contribution margin of $112 but it requires 8 minutes per unit. Therefore, 112/8 = 14. This means its contribution margin is $14 per minute.
Since we have 60,000 machine minutes, we would want to spend them in the most efficient way possible.
So,
If we produce only product L:
60,000 min * $12 per min = $720,000 total contribution margin
If we produce only product C:
60,000 min * $14 per min = $840,000 total contribution margin
