The cost, C, in dollars of producing a particular brand of snack bars is modeled by C (:13) = 2500 + 2:1: 0.00055192 and the revenue from selling these food items is given by R (m) = 4.25 :1: 1. a) Determine the cost of producing 1000 snack bars. b) Determine the revenue in selling 1000 snack bars. 2. a) Determine C'(x). What does this function represent? b) What is the maximum cost and at what x value is this obtained? c) How is C'(1000) different from C'(2500)? 3. a) Determine R'(x). What does this function represent? b) Determine R'(x) at x = 1000. 4. a) Write the profit function as R(x) - C(x). b) Determine P'(x) and explain its meaning. c) When is the profit function positive? Why is this important
