To calculate the predetermined overhead rate, we add the expected total manufacturing overhead costs of both departments and divide it by the expected total machine-hours.

Predetermined overhead rate = (Total expected manufacturing overhead costs) / (Total expected machine-hours)

= (240,000 + 180,000) / (60,000 + 30,000)

= $6 per machine-hour

Now, we need to allocate the manufacturing overhead costs to Job A and Job M based on the machine-hours used in each department. The total machine-hours used in the Molding department for both jobs is 14,400, and in the Finishing department, it is 7,200.

Manufacturing overhead costs for Job A = (14,400 machine-hours x $6 predetermined overhead rate) x 70% (because 70% of the total machine-hours are in the Molding department)

= $60,480

Manufacturing overhead costs for Job M = (7,200 machine-hours x $6 predetermined overhead rate) x 50% (because 50% of the total machine-hours are in the Finishing department)

= $21,600

Total manufacturing costs for Job A = Direct materials + Direct labor + Manufacturing overhead

= $28,000 + $16,000 + $60,480

= $104,480

Total manufacturing costs for Job M = Direct materials + Direct labor + Manufacturing overhead

= $31,000 + $23,000 + $21,600

= $75,600

The markup on manufacturing cost is 30%, so the selling price for Job A is:

Selling price for Job A = Total manufacturing costs x (1 + Markup percentage)

= $104,480 x 1.30

= $135,824

Therefore, the calculated selling price for Job A is closest to $78,533 (rounded to the nearest whole dollar).
