Explanation:

1. Calculation to determine how much of an overtime premium per hour should the company be willing to pay.

Selling price per unit$1,750

Less Variable cost per unit ($1,200)

Contribution margin per unit (a)$550

Upholstery shop time required to produce one unit (b)10 hours

Contribution margin per unit of the constrained resource (a) ÷ (b)$55 per hour

($550/10 hours)

Therefore the Maximum overtime premium per hour will be $55 per hour

Selling price per unit$1,190

Less Variable cost per unit ($850)

Contribution margin per unit (a)$340

Upholstery shop time required to produce one unit (b)4hours

Contribution margin per unit of the constrained resource (a) ÷ (b)$85 per hour

($340/4 hours )

Now let calculate The additional contribution margin per hour earned by hiring the nearby company

Additional contribution margin per hour earned= $85 – $44

Additional contribution margin per hour earned= $41 per hour

Therefore The additional contribution margin per hour earned by hiring the nearby company will be $41 per hour
