Requirements 1 and 2 please!

Make or Buy?
	Ledfords is a chain of improvement stores. Suppose Ledfords is trying to decide whether to produce its own line of Formica countertops,
	cabinets, and picnic tables. Assume Ledford would incur the following unit costs in producing its own product lines:
			Countertops	Cabinets	Picnic Tables
		Direct materials per unit	$15	$10	$25
		Direct labor per unit	10	5	15
		Variable manufacturing overhead per unit	5	2	6
	Rather than making these products, assume that Ledfords could buy them from outside suppliers. Suppliers would charge Ledfords $40 per
	countertop, $25 per cabinet, and $65 per picnic table. Whether Ledfords makes or buys these products, assume that the company
	expects the following annual sales:
		Countertops -- 487,200 at $130 each
		Cabinets -- 150,000 at $75 each
		Picnic tables -- 100,000 at $225 each
	Assume that Ledfords has a production facility with excess capacity that could be used to produce these products with no additional
	fixed costs. If making is sufficiently more profitable than outsourcing, Ledfords will start production of the new lines of products. The
	president of Ledfords has asked your consulting group for a recommendation.
		Requirements
1.)		Are the following items relevant or irrelevant in Ledfords's decision to build a new plant that will manufacture its own products?
	a.)	The unit sales price of the countertops, cabinets, and picnic tables (the sales prices that Ledfords charges its customers)
	b.)	The prices outside suppliers would charge Ledfords for the three products if Ledfords decides to outsource the products rather than
		make them.
	c.)	The direct materials, direct labor, and variable overhead Ledfords would incur to manufacture the three product lines
	d.)	The president's salary
2.)		Determine whether Ledfords should make or outsource the countertops, cabinets, and picnic tables. In other words, what is the
		annual difference in operating income if Ledfords decides to make rather than outsource each of these three products?
