Nurally Inc. manufactures a single product. Selected data from the company€™s cost records for two recent months are given below:

The company€™s manufacturing overhead cost consists of both variable and fixed cost elements. To have data available for planning, management wants to determine how much of the over- head cost is variable with units produced and how much of it is fixed per year.
Required:
1. For both July and October, estimate the amount of manufacturing overhead cost added to production. The company had no underapplied or overapplied overhead in either month.
2. Using the high€“low method, estimate a cost formula for manufacturing overhead. Express the variable portion of the formula in terms of a variable rate per unit of product.
3. If 9,500 units are produced during a month, what will the cost of goods manufactured be? (Assume that the company€™s beginning work in process inventory for the month is $16,000 and that its ending work in process inventory is $19,000. Also assume that there is no underapplied or overapplied overhead cost for the month.)
