Notes:

1. Manufacturing overhead is allocated to products at a predetermined rate based on direct labour in dollars.

Budgeted overhead= $3,075,000*Budgeted direct labour$279,500= $11.00 per dollar of direct labour hour cost*90% of total overhead is composed of depreciation, regular machine maintenance, related salaries, and other fixed manufacturing costs. The remaining 10% of overhead costs is variable and includes the costs of operating the machines.2. Variable selling and administrative costs consist entirely of sales commissions. Commission amounts per unit were negotiated with the salespeople two years ago.3. Fixed selling and administrative costs are allocated to products at a predetermined rate based on total manufacturing costs.

Budgeted fixed selling and administrative costs =$184,260Budgeted total manufacturing costs$6,142,000= 3% of manufacturing costs
