Real Cool produces two different models of air conditioners. The company produces the mechanical systems in their components department. The mechanical systems are combined with the housing assembly in its finishing department. The activities, costs, and drivers associated with these two manufacturing processes and the production support process follow. (Round OH rate and cost per unit answers to 2 decimal places.)

Required:
1. Using a plantwide overhead rate based on machine hours, compute the overhead cost per unit for each product line.
2. Determine the total cost per unit for each products line if the direct labor and direct materials costs per unit are $220 for Model 145 and $150 for Model 212.
3. Assume if the market price for Model 145 is $755 and the market price for Model 212 is $590, determine the profit or loss per unit for each model.

1. Plantwide Overhead Rate $ 220.06 per machine hour

Total Cost per Unit= Model 145 $ 555.96 per unit

Total cost per unit = Model 212 $ 616.94 per unit

Profit (loss)    Model 145  219.04

Loss Model 212  (26.94)

We find the plantwide overhead rate by dividing the total overhead with the total machine hours.

1. Plantwide Overhead Rate= Total Factory Overhead/ Total Machine Hours

Plantwide Overhead Rate= $981,200+ $472,350+$227,710/7640

                                       = 1681260/7640= $ 220.06 per machine hour

We multiply the machine hours of each model to get the overhead .

2.  Cost of Model 145

Materials and Labor  = $220 *1500= $330,000

Overhead = $220.06 *2290= $503,937.4

Total Cost = $83,3937.4

Total Cost per Unit= $83,3937.4/1500= $ 555.96 per unit

Cost Of Model 212

Materials and Labor  = $150 *3000= $ 450,000

Overhead = $220.06 *6350= $ 1400,810

Total Cost = $ 1850810

Total cost per unit = $ 1850810/ 3000= $ 616.94 per unit

We find the profit or loss by subtracting the mfg cost from the market value.
