Question 795500
in manufacturing a component for a machine, the initial cost of die is $850 and all other additional costs are $3 per unit produced. 
.
(a) Express the total cost C ( in dollars) as a linear function of the number q of units produced. 
"cost" = "$3 per unit" + "start up"
C = 3q + 850
.
(b) How many units are produced if the total cost is $1600
replace C with 1600 and solve for q:
1600 = 3q + 850
750 = 3q
250 units = q
