Velshi Printers

Answer the following questions using the information below:
Velshi Printers has contracts to complete weekly supplements required by forty-six customers. For the year 2015, manufacturing overhead cost estimates total $840,000 for an annual production capacity of 12 million pages.
For 2015 Velshi Printers has decided to evaluate the use of additional cost pools. After analyzing manufacturing overhead costs, it was determined that number of design changes, setups, and inspections are the primary manufacturing overhead cost drivers. The following information was gathered during the analysis:
$$\begin{array} { l cc } \text { Cost pool } & \text { Manufacturing overhead costs } & \text { Activity level } \\\text { Design changes } & \$ 120,000 & 300 \text { design changes } \\\text { Setups } & 640,000 & 5,000 \text { setups } \\\text { Inspections } & \underline{80,000} & 8,000 \text { inspections } \\\text { Total manufacturing overhead costs } & \$ 840,000 &\end{array}$$ During 2015, two customers, Money Managers and Hospital Systems, are expected to use the following printing services:
$$\begin{array} { l r r } \text { Activity } & \text { Money Managers } & \text { Hospital Systems } \\\text { Pages } & 60,000 & 76,000 \\\text { Design changes } & 10 & 0 \\\text { Setups } & 20 & 10 \\\text { Inspections } & 30 & 38\end{array}$$
-Assuming activity-cost pools are used,what are the activity-cost driver rates for design changes,setups,and inspections cost pools?

A) $400 per change, $128 per setup, $10 per inspection
B) $360 per change, $320 per setup, $6.40 per inspection
C) $168 per change, $538 per setup, $42 per inspection
D) $286 per change, $152 per setup, $20 per inspection
