July's overhead costs were $174.500 for machine supplies, $24.800 for property taxes, and $1,160,000 for plant maintenance Required: A. Determine the machine supplies and property taxes for May B. By using the high-low method, analyze Colorado's plant maintenance cost and calculate the monthly fixed portion and the variable cost per machine hour. c. Assume that present cost behavior patterns continue into future months. Estimate the total amount of manufacturing overhead the company can expect in September if 57.600 machine hours are worked. Note: For all requirements, round intermediate rate calculations to 2 decimal places and all other intermediate calculations to the nearest whole dollar. Round your final answers for "Variable plant maintenance" to 2 decimal places and all other calculations to the nearest whole dollar
