Vista Company manufactures electronic equipment. It currently purchases the special switches used in each of its products from an outside supplier. The supplier charges Vista $4.20 per switch. Vistas CEO is considering purchasing either machine A or machine B so the company can manufacture its own switches. The projected data are as follows:

..

	Machine A	Machine B
Annual fixed costs	$ 429,000	$ 579,600
Variable cost per switch	1.34	0.60
