Answer:
23.12%
Explanation:
Internal rate of return (IRR) is the rate at which the Net present value (NPV) of a project equals to zero.
Using a financial calculator and the CF function, input the following to find IRR;
Initial investment; CF0 = -1,200,000
Yr1 cashflow inflow ; C01 = 235,000
Yr2 cashflow inflow ; C02 = 412,300
Yr3 cashflow inflow ; C03 = 665,000
Yr4 cashflow inflow ; C04 = 875,000
Then key in IRR CPT = 23.119%
Therefore, the Internal rate of return this expansion is 23.12%
