please answer this AND DRAW THE CASH FLOW DIAGRAM.

A shopping center is contracting snow removal from its parking lots at a cost of $430/day. However, a snow-removal machine can be purchased for $24,000 with an estimated useful life of 6 years, but no salvage value. The annual operating and maintaining costs are estimated as $4,500. Assuming a MARR of 12% and using cash flow diagrams (20-points) AND calculations (25-points) determine the break-even value for the number of days per year that snow removal is required to justify purchasing the snow-removal machine. >
