The given information:

The quantity is 20,000 units, the price is $15, and the labor cost is $250,000. The capital worth is $400,000 and the rate of return is 7%.

The economic profit or loss can be calculated as follows:

Profit=(Price×Quantity)Labor cost(Capital worth×Rate of return)=(15×20,000)250,000(400,000×0.07)=300,000250,00028,000=22,000

Hua Xing runs a lawn care service. Buying an additional riding lawn mower will cost $3,000 but would allow her firm to earn $1,000 of additional revenue each year for the next four years. She expects marginal efficiency of capital to be at least 10%. Which statement is an accurate description of this investment opportunity? a) Hua Xing should make the investment because turning $3,000 into $4,000 provides a rate of return of 33%. b) Hua Xing should not make the investment because it has a negative net present value. c) Hua Xing should not make the investment because it provides only a 5.16% return on investment. Od) Hua Xing should make the investment because the internal rate of return exceeds 10%.
