How to formulate LPP for the below case?

Question 1: 8 Points Formulation The Allied Landscape International (ALI) is a producer of landscape decoration models. ALI's main products are Dragons, Pelicans and Dogs. The following information is provided: - Cost of production, selling price, and expected demand are shown in the following table: - The production process goes through 3 stages. In stage 1 , melted iron is poured in special molds, then cooled and brushed. In stage 2, the design is painted, and in stage 3 the final product is packaged in preparation for safe shipping to the distribution centers. - The company employs 40 workers in stage 1,55 in stage 2, and 20 in stage 3 . Each worker can put up to 40 hours per week. Stage 1 requires 2 hours of labor time per unit of Dragons, 30 minutes per unit of Pelicans, and 1 hour per unit of Dogs. Stage 2 requires 3 hours per unit of Dragons, 2 hours per unit of Pelicans, and 45 minutes per unit of Dogs. Stage 3 requires 30 minutes per unit of each of the three products. - Due to the high competitive market of Dogs, the company must always produce enough to exactly meet the expected demand. - Iron and paint required for production can be easily obtained in short notices from a nearby supplier. Therefore, no apparent limitation is found on the use of row materials. Formulate the linear programming problem that maximizes the weekly selling price of the 3 main products, while limiting the weekly production cost to 50,000
