Required: 1. Estimate how much of the $343,200 factory overhead cost at the high level of activity consists of maintenance cost. (Hint: To do this, it may be helpful to first determine how much of the $343,200 consists of indirect materials and rent. Think about the behavior of variable and fixed costs!) (Do not round Intermediate calculations.) Maintenance cost at high level of activity 2. Using the high-low method, estimate a cost formula for maintenance. (Do not round Intermediato calculations. Round "Variable cost olement" to 2 decimal places.) Direct Labor Maintenance Hours Cost High level of activity Low level of activity Change $ 0 Variable cost element per DLH Fixed cost element YE X 3. What total factory overhead costs would you expect the company to incur at an operating level of 70,290 direct labor-hours? (Do not round intermediate calculations.) Total factory overhead cost
