Implement the following LP problem in a spreadsheet. Use Solver to solve the problem and create a Sensitivity Report. Use this information, to answer the following questions: MAX: $4$X$1+2$X$2$ Subject to: $2$X $+4$X$2203$X$,+<=15$; X$\_\{1\},$ X$\_\{2\}\backslash$ge $0$ a$.$ What range of values can the objective function coefficient for variable X$1$ assume without changing the optimal solution? $1\mathrm{.}2$ to$+$V b$.$ Is the optimal solution to this problem unique, or are there alternate optimal solutions? I. Unique. Only available solution. II$.$ Not unique $.$ One alternative solution. III. Not unique. Two alternative solutions. I c$.$ How much does the objective function coefficient for variable X$2$ have to increase before it enters the optimal solution at a strictly positive level? Round your answer two decimal places. It has to increase by at least $2\mathrm{.}50$ d$.$ What is the optimal objective function value if X$2$ equals $1?$ Round your answer to two decimal places. $16\mathrm{.}0040\mathrm{.}00$ e$.$ What is the optimal objective function value if the RHS value for the second constraint changes from $15$ to $25?$ Round your answer to two decimal places.
