Answer:
x = 7%
Explanation:
given data:
price of equipment is given as $30 978
cash inflow is given a $3900/ year for a period of 12 years
Let internal rate of return is x %
we know , at IRR, inflow value of PV = outflow value of PV
[tex]30978 = \frac{3900}{1 \times x} + \frac{3900}{1 \times x^2} + \frac{3900}{1 \times x^3} +....+ \frac{3900}{1 \times x^{12}}[/tex]
from using financial calculator x value will be
x = 7%
