A companys total overhead cost at various levels of activity is presented below:

Month	Machine-Hours	Total Overhead Cost
March ......................................	2,000	$18,000
April .........................................	5,000	$28,500
May .........................................	6,000	$32,000
June ........................................	4,000	$25,000

Assume that the overhead cost above consists of direct materials, supervisory salaries, and utilities. The breakdown of these costs at the 6,000 machine-hour level of activity is as follows:

Direct Materials (variable) .............................	$12,000
Supervisory salaries (fixed) ...................	?
Utilities (mixed) .....................................	12,000
Total overhead cost ..............................	?

Suppose the company uses the high-low method to estimate a cost formula for utilities. What is the total utilities cost the company expects to incur at an activity level of 6,500 machine hours?
