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 .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.
