Your company wants to create a customer facing website. Analysts estimate it will take about $300$ effective hours on the back end systems, and about $250$ effective hours on the front end systems. Your company doesn't have the expertise to develop the website in$-$house, so the services must be hired out. This project has been allotted $$25,000$ budget. Three developers have offered their services at varying rates, availability, and with admitted efficiencies $($where $\mathrm{.}75$ means "I get about $45$ minutes worth of work done in an hour"$).$ Developers can only work on the systems indicated by "Yes", and cannot work more hours than they have available. Effective hours worked must equal required effective hours. Use solver $($Simplex$,$ not GRG or evolutionary$)$ to find a way to minimize costs by determining how many hours $($only whole hours$)$ to hire each developer. SAVE BEFORE SOLVING!!! Please use the backup solver sheet if you accidentally delete formulas.
