1. The marginal cost function associated with producing x widgets is given by C'(x) = 0.4x + 30 where C'(x) is measured in dollars/unit and x denotes the number of widgets. If the daily fixed costs incurred in the production is $600, compute the total cost incurred in producing the first 100 units of the day. _______dollars
