A manager has to decide how many machines to purchase for a new production facility. Once the machines are purchased, production will start. Estimated monthly fixed cost and production capacity are provided below for each alternative. The unit variable cost and the unit revenue of the product are estimated to be $20 and $50, respectively.

Number of Machines to Purchase	Monthly Fixed Cost	Monthly Total Production Capacity (in units)
1	$18,000	0500
2	$24,000	01,000
3	$30,000	01,500

(a) If only one machine is purchased, what is the monthly production level to break even?

(b) If two machines are purchased, what is the monthly production level to break even?
