Orbit Antenna plans to produce 125 Lo-Gain antennas and 225 Hi-Gain antennas.

Requirements

1. Compute the indirect manufacturing cost per unit using direct labor hours for the single plantwide predetermined overhead allocation rate.

Step by step solution

01

Computation of predetermined overhead rate under single plantwide allocation

$$\begin{gathered} \mathbf{predetermined}\mathbf{}\mathbf{overhead}\mathbf{}\mathbf{rate}\mathbf{}\mathbf{=}\frac{\mathbf{total}\mathbf{}\mathbf{indirect}\mathbf{}\mathbf{manufacturing}\mathbf{}\mathbf{cost}}{\mathbf{total}\mathbf{}\mathbf{direct}\mathbf{}\mathbf{labor}\mathbf{}\mathbf{hours}} \\ \mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{=}\frac{\mathbf{\$}\mathbf{88}\mathbf{,}\mathbf{000}}{\mathbf{5}\mathbf{,}\mathbf{000}} \\ \mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{=}\mathbf{\$}\mathbf{17}\mathbf{.}\mathbf{6} \end{gathered}$$

02

Computation of per unit indirect cost for Lo-Gain

$$\begin{gathered} \mathbf{per}\mathbf{}\mathbf{unit}\mathbf{}\mathbf{indirect}\mathbf{}\mathbf{cost}\mathbf{}\mathbf{=}\frac{\mathbf{predetermined}\mathbf{}\mathbf{overhead}\mathbf{}\mathbf{rate}\mathbf{\times }\mathbf{no}\mathbf{.}\mathbf{of}\mathbf{}\mathbf{direct}\mathbf{}\mathbf{labor}\mathbf{}\mathbf{hour}\mathbf{}\mathbf{required}\mathbf{}}{\mathbf{no}\mathbf{.}\mathbf{of}\mathbf{}\mathbf{units}\mathbf{}\mathbf{produced}} \\ \mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{=}\frac{\mathbf{\$}\mathbf{17}\mathbf{.}\mathbf{6}\mathbf{\times }\mathbf{1}\mathbf{,}\mathbf{200}}{\mathbf{125}} \\ \mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{=}\frac{\mathbf{\$}\mathbf{21}\mathbf{,}\mathbf{120}}{\mathbf{125}} \\ \mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{=}\mathbf{\$}\mathbf{168}\mathbf{.}\mathbf{96} \end{gathered}$$

03

Computation of per unit indirect cost for Hi-Gain

$$\begin{gathered} \mathbf{per}\mathbf{}\mathbf{unit}\mathbf{}\mathbf{indirect}\mathbf{}\mathbf{cost}\mathbf{}\mathbf{=}\frac{\mathbf{predetermined}\mathbf{}\mathbf{overhead}\mathbf{}\mathbf{rate}\mathbf{\times }\mathbf{no}\mathbf{.}\mathbf{of}\mathbf{}\mathbf{direct}\mathbf{}\mathbf{labor}\mathbf{}\mathbf{hour}\mathbf{}\mathbf{required}\mathbf{}}{\mathbf{no}\mathbf{.}\mathbf{of}\mathbf{}\mathbf{units}\mathbf{}\mathbf{produced}} \\ \mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{=}\frac{\mathbf{\$}\mathbf{17}\mathbf{.}\mathbf{6}\mathbf{\times }\mathbf{3}\mathbf{,}\mathbf{800}}{\mathbf{225}} \\ \mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{=}\frac{\mathbf{\$}\mathbf{66}\mathbf{,}\mathbf{880}}{\mathbf{225}} \\ \mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{}\mathbf{=}\mathbf{\$}\mathbf{297}\mathbf{.}\mathbf{24} \end{gathered}$$
