CDC Hospital must decide between two slightly different types of technology and vendors for their X-ray equipment. The expected demand for either of these machines is 11,000 X-rays per year. Vendor A offers a Fixed X-ray machine with an upfront one-time fee of $200,000 and a variable cost per X-ray of $18.6. Vendor B offers a mobile X-ray machine with a one-time fee of $100,000 and a variable cost per X-ray of $21.00. What will be the cost difference between these two vendors? Can the result of this problem be done in Excel as well.
