Pls help me correct the wrong numbers

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: Airplane Flight Resource Hours Total Cost Airplane depreciation: High 44,000 $ 18,800,000 Low 28,000 $ 18,800,000 Fuel: High 44,000 445,896,000 Low 28,000 283,752,000 Airplane maintenance: High 44,000 16,560,000 Low 28,000 12,152,000 5. What is the variable rate for airplane maintenance? $ 276 per flight hour What is the fixed cost for airplane maintenance? $ 4,424,000 X 6. What is the cost formula for airplane maintenance? Total cost of airplane maintenance = $ 4,424,000 X 276 x Number of airplane flight hours) + ($ 7. Using the three cost formulas that you developed, predict the cost of each resource in a month with 36,000 airplane flight hours. (Note: Do not round intermediate calculations.) Total cost of airplane depreciation $ 18,800,000 Total cost of fuel $ 364,824,000 Total cost of airplane maintenance 14,360,000 X
