Use Problem $6-15$ and Excel to solve Problem $6-32$ please. Thank you :) $20.6-32$ Consider the staffing situation faced by the Gaubert Marketing Company in Problem $6-15.$ Ignore the salary and part$-$time information given in part $($b$)$ of that problem. Develop a schedule that meets the daily employee requirements and satisfices the following three weighted goals: Goal $1$: Use at most $27$ total employees weight $=50$ Goal $2$: Minimize the excess employees scheduled on Saturday weight $=30$ Goal $3$: Minimize the excess employees scheduled on Sunday weight $=203.6-15$ The Gaubert Marketing Company needs the following number of telemarketers on the phones during the upcoming week: Monday $23,$ Tuesday $16,$ Wednesday $21,$ Thursday $17,$ Friday $20,$ Saturday $12,$ and Sunday $15.$ Each employee works five consecutive days followed by $2$ days off per week. How many telemarketers should be scheduled each day of the week to begin their five$-$day work week? The objective is to minimize the total number of employees needed to fulfill the daily requirements. a$.$ Solve as an IP model. b$.$ Additional information is now available for Gaubert. Daily pay from Monday through Friday is $$90,$ pay for Saturday is $$110,$ and Sunday workers earn $$125.$ In addition, up to four people can be hired who will work Friday, Saturday, and Sunday. Their pay for this three$-$day week is $$250.$ The new objective is to minimize total weekly labor costs. Revise the IP model and solve it$.$
