Global Enterprises has identified three cost pools and three corresponding cost drivers to allocate overhead costs. The following estimates are provided for the coming year:

Supervision of direct labor $$480,000$ Direct labor$-$hours $800,000$

Machine maintenance $$220,000$ Machine$-$hours $550,000$

Facility rent $$260,000$ Square feet of area $100,000$

The accounting records show the Leaf Job consumed the following resources:

Cost Driver Activity Level

Direct labor$-$hours $600$

Machine$-$hours $2,100$
