A shopping center is considering paying $15,000 for a snow plow and blower, which will have a 5 year life, a negligible salvage value, and daily O&M expenses of $150. The firm can alternatively contract to have the snow removed at a cost of $450/day. With a MARR of 10%, how many days a year must the snow plow and blower be used in order to justify the purchase?
Use the EUAC method to calculate your answer.
Enter only the number of days in your answer with no rounding (NOTE: this is a multi-part problem, so solve the parts in sequence.
Omit symbols ($, %, -, etc.) in your answer.)
