Answer: The total manufacturing cost per ceiling fan is $96.4 
Step-by-step explanation:
Hi, to calculate the total manufacturing cost per ceiling fan we have to sum: 
Direct material cost + number of parts (cost per part handling) + machine hours (cost of each machine hour) 
Replacing with the values given 
70 + 20 (0.08) + 4 (6.20) = 70 +1.6+24.8= $96.4 
The total manufacturing cost per ceiling fan is $96.4
