Answer:
8.41%
Explanation:
We have to applied the rate formula that is presented in the attachment.
The NPER reflects the time period.
Provided that,
Present value = $120,000
Future value or Face value = $0
PMT = $15,000
NPER =12 years
The formula is shown below:
= Rate(NPER;PMT;-PV;FV;type)
After solving this, the rate of return is 8.41%
