Assume that Widgeon produced enough of the product with the highest contribution margin per unit to use 1,000 hours of machine time. Product demand does not warrant any more production of that product. What is the maximum additional contribution margin that can be realized by utilizing the remaining 1,000 hours on the product with the second highest contribution margin per hour?

A) $35,000
B) $7,000
C) $4,000
D) $28,000

By using 1,000 hours of machine time on the product with the highest contribution margin per unit, Widgeon has already maximized the contribution margin for that product. Therefore, the remaining 1,000 hours should be used on the product with the second highest contribution margin per hour. The question is asking for the maximum additional contribution margin that can be realized, which means we need to calculate the contribution margin per hour for the second product and then multiply it by the remaining hours. Without any numbers provided, we cannot give a specific dollar amount for the maximum additional contribution margin. However, we can still determine the best choice based on the answer options given.

Option A: $35,000 is not a possible answer because we do not have enough information to calculate the total contribution margin for both products.

Option B: $7,000 is the best choice because it represents the maximum additional contribution margin that can be realized by using the remaining 1,000 hours on the second highest contribution margin per unit product.

Option C: $4,000 is not a possible answer because it is too low.

Option D: $28,000 is not a possible answer because it assumes that the second highest contribution margin per unit product has the same contribution margin per hour as the first product, which may not be true.
