From section 8.2 question 9, tell which size boxes will minimize total cost if fixed cost =5000

here is the question and the table from your textbook

FIXED COST = 5000 17 18 19 24 26 30 33 M 26 M M M 30 M M M M M 0 L / / SIZE DEMAND 17 200 18 400 19 200 24 700 26 500 30 300 33 400 A company sells seven types of boxes, ranging in volume from 17 to 33 cubic feet. The demand and size of each box is given in Table 7. The variable cost (in dollars) of producing each box is equal to the box's volume. A fixed cost of $1,000 is incurred to produce any of a particular box. If the company desires, demand for a box may be satisfied by a box of larger size. Formulate and solve a shortest-path problem whose solution will minimize the cost of meeting the demand for boxes.
