Answer:
12.28%
Step-by-step explanation:
In this question, we use the Rate formula which is shown in the spreadsheet. 
The NPER represents the time period. 
Given that, 
Present value = $1,407 
Future value or Face value = $1,000 
PMT = $1,000 × 20% = $200
NPER = 9 years
The formula is shown below: 
= Rate(NPER;PMT;-PV;FV;type) 
The present value come in negative 
So, after solving this, the answer would be 12.28%
