Solve this model using Excel Solver $($keep in mind that you must set up a linear programming

model in Excel Solver$).$ In other words, what would be the $(1)$ maximum ending balance, and $(2)$

optimal level of participation rate for each project? Explain using at least $50$ words.

b$.$ How would the results in part a change if Samsung has $$11$ million available now and expects

to receive $$7$ million from other projects by the end of each year? In other words, what would be

the maximum ending balance and optimal level of participation rate for each project in a new

situation? $($Now$,$ you must run a new linear programming model by replacing $$10$ million

$($current starting balance$)$ by $$11$ million $($new starting balance$)$ and $$6$ million $($current value of

other project$)$ by $$7$ million $($new value of other project$).$ Explain the results using at least $50$

words.
