please solve Question 2 according to the book: "Production and Operations Analysis. Steven Nahmias and Tava Lennon Oslen. 8th Ed. Waveland press. Follw the steps for the solved example in the screenshot

Question 2: Anticipated demands for a four-period planning horizon are 14, 3,26, 15. Current starting inventory is four units and the inventory manager would like to have eight units on hand at the end of the planning horizon. Assume h=$1 per unit per period and K = $30. Find the optimal production schedule using Path Enumeration. (Hint: Modify the first and last periods demands to account for starting and ending inventory.)

Solving by Enumeration r=(52,87,23,56) Solving by Enumeration r=(52,87,23,56) Optimal path: 1-2-4 at a cost of $248 (order in periods 1, 2, 4 only) y1=52,y2=110andy4=56
