Answer:
e) 14.19%
Step-by-step explanation:
Let IRR be x% . At IRR, Present value of inflows = Present value of outflows.
167,000 = 22000/1.0x + 22000/1.0x^2 + 22000/1.0x^3 + 22000/1.0x^4 + 22000/1.0x^5 + 30,000/1.0x^6 + 30,000/1.0x^7 + 30,000/1.0x^8 + 30,000/1.0x^9 + 30,000/1.0x^10 + 43000/1.0x^11 + 43000/1.0x^12 + 43000/1.0x^13 + 43000/1.0x^14 + 43000/1.0x^15
x = 0.1419
x = 14.19%
Hence, the internal rate of return for the project is 14.19%
