Answer:
18% and 24.01%
Explanation:
The computation of the internal rate of return for each machine is shown below:
Let us assume the Internal rate of return be X
And as we know that
The present value of cash inflows = present value of cash outflows
For Machine A
So,
$2,000 = $3877 ÷ 1.0x^4
So X = IRR = 18%
For Machine B
$2,000 = $832 ÷ 1.0x + $832 ÷ 1.0x^2 + $832 ÷ 1.0x^3 + $832 ÷ 1.0x^4
So X = IRR = 24.01%
