Why or why not? o) Assume that due to unforeseen circumstances, the availability of resource 3 drops from 45000 to 40000. How would such unexpected drop impact the company's production policy? P) Assess the impact of changing the following selling prices, one at a time, on the current optimal solution, by just indicating whether the current optimal solution remains optimal or not, and why: 1) Increasing the selling price of PS-V4 from S126 to $135. 2) Reducing the selling price of P8-V3 from $100 to $90. 3) Increasing the selling price of P10-v5 from $93 to $105. 2) If the company could sell as much as it produces from one particular product (i.e. no maximum files restriction), which product would that be, and why? (show detailed analysis) 1) Now, as pati of a marketing campaign, let us say that the company is considering reducing the selling price of all variations from a particular product by 20%, and the anticipated effect would be an increase in the maximum sales of that specific product by 30%. Which product should the company go ahead and reduce its price and why? (show detailed analysis) 3) If a new competitor enters the market, which would reduce the maximum sales of all products equivalently by 15%, what would be the contingent optimal production strategy in this case, and what is the impact on the company's total profit?

PRBLEM DESCRIPTION: 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.
