Changing the Cost Formula for a Month to the Cost Formula for a Year 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 airpiane flight hours is the driver. The total costs of the three resources and the related number of airplane flight hours are as follows: Required: 1. Develop an annual cost formula for airplane depreciation. 1. Develop an annual cost formula for airplane depreciation. Total annual cost of airplane depreciation = x($ Develop an annual cost formula for fuel. Total annual cost of fuel =$ Develop an annual cost formula for airplane maintenance. Total annual cost of airplane maintenance =( $)+($ 2. Using the three annual cost formulas that you developed, predict the cost of each resource in a year with 480,000 airplane fight hours. Total annual cost of airplane depreciation Total annual cost of fuel Total annual cost of airplane maintenance
