You own a small firm and would like to accommodate employees who own electric vehicles by installing a professional-grade charging station. You would like to install one of these machines in the parking lot. Employees would reserve time for charging. You do some initial research and have identified three options. The grant you are applying for will reimburse you $20 for each charge. This would be like revenue. You expect that your employees will use 960 charges per year. Option 1: Purchase the EvoCharge for a cost of $4,840 and a per-unit charging cost of $16.10 per charge. Option 2: Purchase the Gilbarco for a cost of $7,950 and a per-unit charging cost of $11.50 per charge. Option 3: Purchase a Levitonfor $11,950 and a per-unit charging cost of $9.00 per charge. This will be a one-year trial after which there will be more information available for the bigger decision on continuing or expanding. What is the Breakeven Volume between Option 1 and Option 3? You should calculate this answer, but be sure you verify with your graph. Express as whole number
