During the past year, the high and low use of three different resources for Fly High Airlines occurred in July and April. The resources are airplane depreciation, fuel, and airplane maintenance. The number of airplane flight hours is the driver. The total costs of the three resources and the related number of airplane flight hours are as follows:

Resource	Airplane Flight Hours			Total Cost
Airplane depreciation:
High	44,000			$ 18,100,000
Low	28,000			$ 18,100,000
Fuel:
High	44,000			445,896,000
Low	28,000			283,752,000
Airplane maintenance:
High	44,000			16,688,000
Low	28,000			11,568,000

Required:

If required, round answers to nearest dollar. Except round variable rate per hour to the nearest cent.

1. Develop an annual cost formula for airplane depreciation.

Total annual cost of airplane depreciation = fill in the blank 1 x ( $fill in the blank 2 )

Develop an annual cost formula for fuel.

Total annual cost of fuel = $fill in the blank 3

Develop an annual cost formula for airplane maintenance.

Total annual cost of airplane maintenance = (fill in the blank 5 x $fill in the blank 6 ) + ( $fill in the blank 7
