Final answer:
The internal rate of return for the equipment purchase is approximately 10.7%.
Step-by-step explanation:
To calculate the internal rate of return, we can use the cash inflows and the initial cost of the equipment. In this case, we have a cash inflow of $1,000 per year for 10 years, and the initial cost of the equipment is $7,360. We need to find the discount rate that makes the net present value of these cash flows equal to zero.
Using a financial calculator or spreadsheet, we can input the cash flows and solve for the internal rate of return (IRR). In this case, the internal rate of return is approximately 10.7%.
