In model $5-3,$ Consider a scenario in which you manage a system with three expandable resources: trunk lines, all$-$product tech$-$support people, and salespeople. You have received an order from above, granting you an additional $$1,200$ per week to allocate towards these resources. The weekly costs for each resource are as follows:

$$ Trunk lines: $$100$ each

All$-$product tech$-$support people: $$150$ each

$$ Salespeople: $$200$ each

However, there is a desk space limitation$,$ allowing for a maximum of $4$ people $($salespeople and tech$-$support people combined$).$ Your task is to determine the optimal allocation of the new funds across these resources.

a$)$ Generate at least $6$ scenarios, varying the distribution of the additional budget among the three resources. Then, using the Performance Analyzer $($PAN$),$ run all scenarios simultaneously and identify the one with the minimum values for both "percent rejected" and "Total Cost."

b$)$ Create two bar charts$-$ one for "percent rejected" and another for "Total Cost" $$to visually represent the outcomes of the different scenarios. Provide a brief description of each chart."
