Answer: $7.20 per minute
Step-by-step explanation:
Find out the profitability of each product as Contribution Margin per minute.
Magnifico
Contribution margin per minute = (Selling price - Variable cost) / minutes on the constraint
= (335.18 - 259.26) / 7.5
= $10.12 per minute
Bellissimo
= (228.46 - 173.08) / 4.3
= $12.88 per minute
Lovely
= (199.21 - 159.61) / 5.5
= $7.20 per minute
Their least profitable product is $7.20 per minute.
The machine does not have sufficient time to satisfy the needs of Lovely so they will have to pay more to acquire more of the resource but they should not pay anything more than $7.20 per minute as this is their contribution margin for the product. and anything more would result in a loss.
Options are most probably for another variant of the question.
