solve this question clearly and correctly. solve the model using lingo. and answer the following questions correctly.
A company produces 10 products in 7 different variations of each product. There are three scarce resources that are used to varying degrees to make these product Variations, where the resource requirements per unit of the different products variations are shown in the following tables. os Table 1.

Also, there is limited availability of the three resources, where 33000 units are available from resource 1, 41000 from resource 2, and 45000 units from resource 3. The company is seeking to determine the monthly product/variation mix that maximizes the profit. After surveying the market and taking into account the existence of other competitors who produce similar products, the company anticipates that its monthly saled of the respective products (from all variations) won't exceed a maximum amount as shown in the following table.
