Answer:
lower than 4.53%
Step-by-step explanation:
To determine whether the project is viable, we will use the Internal Rate of Return (IRR). This is the rate at which the Net Present Value (NPV) becomes Nil. In other words, the point at which the discounted net cash outflows are equal to the discounted net cash inflows
In this question, there is one outflow of cash worth $220 million at the start of the project (t=0) and one inflow of $300 million in 7 years.
To calculate IRR, we will use the following formula:.
220 = [300 / ((1+r)^7)]
Solving for r, we find that the interest rate is 4.53%.
Given the cash flows, the project should be accepted at all rates below 4.53% as it will create value for the company.
