Right now is August 1, 2023. You would like to construct an aggregate production plan for product PX27 for January 2024 through July 2024. Cost of regular-time production =72$/u. Cost of overtime production =92$/u. Inventory holding cost =3$/u/mon. Cost of increasing regular production =20$/u. Cost of decreasing regular production = 40$/u. The regular-time production in December 2023 will be 2,154u. The inventory a the end of December 2023 is estimated to be 129u. The forecasted demand (in units) in January 2024 through July 2024 are: 1,673,1,815,1,973,2,253,1,660,1,909,2,000 You want to use the level production strategy with overtime production. Furthermore, you will keep inventory as low as possible but stock-outs must be avoided. Suppose you keep the monthly regular-time production constant at 1,658 units and add overtime production if necessary. You must perform the needed calculation and answer the question shown below. NOTE: Do not use any comma in your answers. The total cost of the above level aggregate production plan is dollars
