Answer:
So first we have to figure out what $1200 per month for 12 months is since it was a year. 1200x12=14,400 a year which is outrageous for an apartment just saying.
Then we find out what 12% of the 1200 is and then add it to 1200.
To find the percentage of that we need to know how many times 12 fits into 100% 12 fits into 100 a total of 8.33333333333 times.
So now we divide 1200 by 8.33333333333 to see what 12% of it is.
1200 divided by 8.33333333333 is 144. So 1200+144=1344.
Now since one of the nine years has passed already we only have 8 remaining.
Now we see what 1344 a month for 12 months is 16,128 a year.
Now we multiply 16,128 by 8 to get the outcome of 8 more years. So 16,128x8=129,024
