Require: If HHRI uses a plant-wide rate based on a single cost
pool, please calculate full cost for both machine hours and direct
labor hours. (10 points)
Hint: When a single cost pool is used, the planned cost per batch is the same whichever cost driver is employed, because ultimately, all overheads have to be charged to production
