Hi there
total manufacturing cost=direct material cost+direct labor cost+ manufacturing OH applied
Direct material=300000
Direct labor=15×12,000=180,000
Manufacturing OH applied=
25×11,500=287,500
total manufacturing cost
300,000+180,000+287,500=767,500
So
total manufacturing cost per unit is
767,500÷60,000=12.8 round your answer to get 13 per unit
The answer is 13 per unit
Good luck!
