Vista Company manufactures electronic equipment. In 2015, it purchased from an outside supplier the special switches used in each of its products. The supplier charged Vista $2.80 per switch. As an alternative, Vista's CEO considered purchasing either machine A or machine B so the company could manufacture its own switches. The CEO decided at the beginning of 2016 to purchase machine A, based on the following data:

Annual fixed cost:

Machine A

(depreciation) $143,000

Variable cost per switch 0.80

Machine B

(depreciation)$212,000

Variable cost per switch 0.35

1. Assume that machine A has not yet been purchased. What is the indifference point between purchasing machine A and purchasing the switches from the outside vendor?

----------------units/year (Do not round intermediate calculations.)

2.

At what volume level should Vista consider replacing machine A with machine B?(Do not round intermediate calculations. Round up your final answer to the nearest whole number.)

__________units per year
