5. Sunny Painting produces both interior and exterior paints from two raw materials, π1τ° and π2τ°. The usage of raw material π1τ° by exterior paint is 6 tons/day and the usage of raw materialπ1τ° by interior paint is 4 tons/day. Similarly, the Usage of raw material π2τ° by exterior paint and interior paint are one and two tons per day, respectively. The daily availabilities of raw materials π1τ° andπ2τ° are limited to 24 and 6 tons, respectively. In order to understand the demand for each product, you developed a market survey. The survey indicates that the daily demand for interior paint cannot exceed that for exterior paint by more than 1 ton. Also, the maximum daily demand for interior paint is 2 tons. The profit per ton is 5 for the exterior and 4 for the interior paint. As the analyst of the Sunny Painting, you want to determine the optimum (best) product mix of interior and exterior paints that maximizes the total daily profit of the company. Formulate this problem: a.Clearly define your variables b.Develop an objective function for the proposed problem c.Write the constraints and label them.
