Exercise 7.
Let \(\cost(q)=5000+23 q\text{.}\)
Solution.
  1. Recall that \(\Mcost(q+1)=\cost(q+1)-\cost(q)\text{.}\)
    The entries in the cells should be
    (See part b for some of the values)
  2. Partial table and the graphs:
  3. The table and the graph indicate that the marginal function is a constant (23 to be precise)
  4. \(\displaystyle \Mcost (q)= 23\)
  5. The cost function is always increasing.
  6. The marginal function is always positive.
