thew Bailey, as manager of Designs by Bailey, is upgrading his CAD software. The high$-$performance $($HP$)$ software rents for $$3,000$ per month per workstation. The standard$-$performance $($SP$)$ ware rents for $$1,600$ per month per workstation. The productivity figures that he has available suggest that the HP software is faster for his kind of design. Therefore, with the HP software he wr d $5$ engineers and with the SP software he will need $6.$ This translates into a variable cost of $$200$ per drawing for the HP system and $$250$ per drawing for the SP system.

is projected that the volume will be $80$ drawings per month, then renting software is the best option available to Matthew.
