Question 1
Creamy Bugs Yogurt has found that the cost, in dollars per pound, of the yogurt it produces, is
C'(x) = -0.003x + 5.50, for x ≤ 300,
where x is the number of pounds of yogurt produced. Find the total cost of producing 280 pounds of yogurt.

Question 2
Decor Woodworkers knows that their marginal cost of producing x feet of custom molding is given by
C'(x) = -0.00003x
2 - 0.05x + 90, for x ≤ 1000,
where C'(x) is in cents. Approximate their total cost, in dollars, of manufacturing 1000 feet of molding, using 4 subintervals over [0, 1000] and the left endpoint of each subinterval.
