The Furniture City (FC) company makes 3 kinds of couches: (1) Standard, (2) Deluxe, and (3) Luxury styles. Each couch goes through 3 production departments: (1) Cutting and Coloring, (2) Assembly, and (3) Finishing. The total number of hours available each month in each of the above departments is 500 . 700 and 400 , respectively. The time (in hours) required by 3 departments for making each couch and the profit per couch are listed below. The company has a contract of supplying at least a total of 150 Standard and Luxury couches per month. The company would like to make a production plan to maximize its total profit. Define S, D, L as the variables for the numbers of Standard, Deluxe and Luxury couches piduced by the company. Then the corresponding LP model is built as follows: Max200S+300D+400L All variables are non-negative. When the above LP model is solved with Excel, we see the following Sensitivity Report. Suppose Sabre, a heavy machinery manufacturer, offers to lease a new assembly machine to FC for 350 additional hours per month. Which lease price(s) below allow(s) FC to make this decision by relying on the sensitivity report alone?
