Answer:

Explanation:

Note that none of the terms in the expression 1 - rate/100*1 - rate/100; is double or float. They are all ints. So the result of the expression will be an int.

Since an int can be assigned to a variable of type int, long, float or double, amount can be int, long, float or double.
