The assignment content discusses the capital budgeting tools used by a restaurant manager to evaluate two investment projects, Project A and Project B. The analysis shows that Project B has a higher internal rate of return (IRR) of 14.5% compared to Project A's IRR of 10%. Additionally, Project B has a higher net present value (NPV) of £92659 compared to Project A's NPV of £68,500. Based on these findings, it is recommended that the restaurant manager invest in Project B as it will yield a higher return and contribute to the firm's productivity and profitability.
