please help answer linear programming (might be bilinear?) - with step by step help with solver. Promise to give thumbs up if you can help me, thanks!

1) Lexmark produces three products: X,Y and Z. The production process uses raw materials, R1, and R2, which are processed on facilities F1 and F2. The following table provides the pertinent data of the problem. a) The minimum daily demand for Y is 20 units, and the maximum demand for Z is 240 units. The unit profit contributions of X,Y and Z are P300,P200, and P500, respectively. Formulate and use Solver to determine optimum solution.

Discuss the feasibility of the following proposal: The per unit profit of Z can be increased by 20%, but this will reduce potential market demand to 210 units instead of the present 240 units.
