Question 1199350: A high-technology electronics firm needs a special microprocessor for use in a microcomputer it manufactures. Three alternatives
have been identified for satisfying its needs. It can purchase the microprocessor from a supplier at a cost of $10 each. The firm can also
purchase one of two pieces of automated equipment and manufacture the microprocessors. One piece of equipment costs $80,000 and would
have variable costs per microprocessor of $8. A more highly automated piece of equipment costs $120, 000 and would result in variable cost of
$5/unit. Determine the minimum cost alternative for different ranges of output.
