Since Product ABC ranks first in terms of contribution margin per minute, the available 13,000 minutes are first allocated to ABC.

ABC –

Required minutes to produce 4,000 units = 16,000

Available minutes                              = 13,000

Shortage                                              3,000 minutes

Maximum Number of units that can be produced with 13,000 minutes = 3,250

Shortage in production = 750 units

Renting of mixing machine from another company provides additional 5,000 units.

Determination of the price the company would be willing to pay for the machine:

Additional 5,000 minutes are first used to meet the 750 units demand of ABC

750 units need 3,000 minutes

Remaining 2,000 minutes are used to produce 400 units of XYZ

Hence the price the company would be willing to pay for the rent of mixing machine is calculated as follows,

ABC    3,000 minutes x $8 per minute           $24,000

XYZ    2,000 minutes x $7.40 per minute      $14,800

Total cost the company is willing to pay       $38,800

Hence, the answer option is D. $38,800
