$650 for 3 years at 9% percentage added.
If 'percentage added' means compunded annually
FV=PV(1+i)^n FV= Future Value PV=Present Value i =decimal interest (.09) n = number of periods (3)
FV=650(1.09)^3=841.77
If it is just simple interest 650(.09)(3)+ 650 = 825.50
After the first year,you would have $650 x (100% base + 9% interest)=650x1.09=$708.5
After the second year,you would have $708.5 x 1.09=$772.27
And at last,you will have a total of $772.27x1.09=$841.77
Spend your $190 interest wisely.
