2. A machine is used to produce two interchangeable products. The daily capacity of the machine can produce at most 20 units of product 1 and 10 units of product 2. Alternatively, the machine can be adjusted to produce at most 12 units of product 1 and 25 units of product 2 daily. Market analysis shows that the maximum daily demand for the two products combined is 35 units. Given that the unit profits for the two respective products are $10 and $12, which of the two machine settings should be selected? Formulate the problem as an ILP and find the optimum. [Note: This two-dimensional problem can be solved by inspecting the graphical solution space. This is not the case for the n-dimensional problem.]
