Consider the three processes described below, which are being evaluated as possible choices to handle production of units for the firm DEF Associates.

PROCESS	FIXED COST ($)	VARIABLE COSTS PER UNIT ($)
			D	1500	1
E	850	5
F	1200	3

(a) Construct a crossover chart to show the comparative total costs of each process, as a function of the volume x of units produced. Your graph should be neat, complete, reasonably scaled, and clearly labeled with all relevant information.

(b) In words, give a summary of which process is best (lowest cost) for which volumes
