Manufacturing overhead totals $3960000 and administrative expenses equal $7400000.
a. Calculate the profit (loss) in total and per unit for each product if overhead is assigned to product using a per-unit basis.
b. Calculate the profit (loss) in total and per unit for each product if overhead is assigned to products using a direct labor hour basis.
c. Assume that manufacturing overhead can be divided into two cost pools as follows: $1320000 which has a cost driver of direct labor hours and $2640000
which has a cost driver of machine hours (totaling 150000). Lawn mower production uses 25000 machine hours; garden tractor production uses 125000 machine
hours. Calculate the profit (loss) in total and per unit for each product if overhead is assigned to products using these two overhead bases.
