need help with compound interest

First bank

Interest is

25000 (1.02)^3  - 25000  = $1530. 20

Second bank

The 25000 will  be worth this much at the end  of the first year :

25000 ( 1 + .043)  = $26075

Then....this amount will be compounded for two  more years at 0.9%....so we have

26075 ( 1 + .009)^2   = $26546. 46

So...the total  amount of interest earned at the second bank  is   $26546.46 - $25000  = $1546.46

The money earns more interest at the second bank
