Answer:
Product A because the contribution margin per MH is $23.33
Step-by-step explanation:
In terms of efficiency, you have to look for the highest outcome with the fewer use of resources. In this case, the resources available are the machines, and the outcome is the profit (margin per unit). Applying the formula: Efficiency producing X (Ex) = [(1 hour of machine hour) / (Product x timed used per unit)]Margin per unit X, and comparing products A and B, you get that producing A is more efficient in terms of profits than producing B, by $10,1 per hour (23,33 - 13,2)
