A firm is considering two investment projects, Y and Z. These projects are NOT mutually exclusive. Assume the firm is not capital constrained. The initial costs and cashflows for these projects are:

Year	Y	Z
0	-50,000	-45,000
1	19,000	10,000
2	17,000	20,000
3	25,000	25,000

(a) Using a discount rate of 10% calculate the net present value for each project. What decision would you make based on your calculations? (4 marks)

(b) How would your decision change if the discount rate used for calculating the net present value is 12%? (4 marks)

(c) Calculate an approximate IRR for each project. Assume the hurdle rate is 10%. What decision would you make based on your calculations?(6 marks)

(d) Calculate the payback period for each project. The company looks to select investment projects paying back in 2 years. What decision would you make based on your calculations?
