The management of Mostly Safe Bungee Manufacturing Corporation believes that machine- hours are an appropriate measure of activity for utility costs. Shown below are machine-hours and total utility costs for the past six months:

	Machine-Hours Used	Utility Cost
Jan	10,000	$30,000
Feb	14,000	$37,500
Mar	20,000	$50,000
Apr	13,000	$36,200
May	17,000	$41,500
Jun	12,000	$34,300

Assume that the relevant range includes all of the activity levels mentioned in this problem.

Using the high-low method, what is Mostly Safe's estimated total fixed utility cost?

Using the variable and fixed costs calculated from the high-low method, what would total costs be for machine hours used of 15,500?
