.

1.  $1500 invested for 3 years at 12% annual interest rate compounded annually


    Future value FV = 1500%2A%281%2B0.12%29%5E3 = $2107.39.



2.  $1500 invested for 3 years at 1% annual interest rate compounded monthly


    Future value FV = 1500%2A%281+%2B+0.01%2F12%29%5E%283%2A12%29 = $1545.66.



3.  You compare.

If the textbook said b), it means that the person, who is responsible for this part in the textbook,
does not understand terminology correctly.

He, probably, interprets part b) as

    Future value FV = 1500%2A%281+%2B+0.01%29%5E%283%2A12%29 = $2146.15.

It is, really, greater than a), but it is called

    $1500 invested for 3 years at 12% annual interest rate compounded monthly.

===========
Interest is usually stated in % per year.
-----
1% per month compounded monthly gives
$1500*(1.01)^36 = $2146.15
---------
It's a poorly written problem.
