2. A man is considering investing P500, 000 to open a semi-automatic auto-washingbusiness in a city of 400, 000 population. The equipment can wash, on the average, 12 carsper hour, using two men to operate it and to do small amount of hand work. The man plansto hire two men, in addition to himself, and operate the station on an 8-hour basis, 6 daysper week, 50 weeks per year. He will pay his employees P25. 00 per hour. He expects tocharge P25. 00 for a car wash. Out-of-pocket miscellaneous cost would be P8, 500 permonth.He would pay his employees for 2 weeks for vacations each year. Because of the length ofhis lease, he must write off his investment within 5 years. His capital now is earning 15%,and he is employed at a steady job that pays P25, 000 per month. He desires a rate ofreturn of at least 20% on his investment. Would you recommend the investment?a) Use ROR method b) Use present worth method c) Use future worth method d) Solve for the payback period and the IRR
1.During a year of operation, a firm collects $5,000,000 (TR) in revenue and spends $3,500,000 (EXPLICIT) on labor expense, raw materials, rent, and utilities.

The explicit costs of the firm are $_________. The implicit costs are $_________. Total economic cost is $__________. b. The firm earns accounting profit of $________. The firm’s economic profit is $_________.
9 The average cost of producing 10 units is Rs 30, while the average cost of producing 20 units is Rs 20. Find the average cost of producing 30 units. {Hint : Find Fixed cost. TC of 10 units = Rs 300, TC of 20 units = Rs 400, VC = Rs 10/ unit Fixed cost = TC = FC + VC (10* 10) = 300 = FC + 100 = FC = 200. Thus, AC of producing 30 units will be Rs 16.67}
