High-Low Method, Cost Formulas the three resources and the related number of airplane flight hours are as follows: Required: Use the high-low method to answer the following questions. If an answer is zero, enter "0". If required, round your answers to nearest dollar. 1. What is the variable rate for airplane depreciation? per flight hour What is the fixed cost for airplane depreciation? 2. What is the cost formula for airplane depreciation? Total cost of airplane depreciation = 3. What is the variable rate for fuel? $ per flight hour What is the fixed cost for fuel? q 4. What is the cost formula for fuel? Total cost of fuel =$ x 5. What is the variable rate for airplane maintenance? per flight hour What is the fixed cost for airplane maintenance? q 6. What is the cost formula for airplane maintenance? Total cost of airplane maintenance = +($ 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.)
