Question 83168
Write a linear cost function and identify all variables used.
A parking garage charges 50cents plus 35cents per half-hour. 


Cost function =  marginal cost * x + fixed cost

c(x) =  35 cents * (x/2) + 50 cents

x is in for an hour


 Marginal cost $90; 150items cost $16,000 to produce

here fixed cost $16,000 and  marginal cost is $90

c(x) = 90 * x + 16000
