To determine the number of digits after the decimal point in the sum, you need to consider the number of decimal places in the numbers being added.

In this case, a whole number is being added to a number with two digits after the decimal point.

When adding a whole number to a decimal number, there is no additional precision gained after the decimal point. The sum will have the same number of decimal places as the number with the most decimal places in the addition.

Since the whole number has no decimal places, it will not affect the number of decimal places in the sum. Therefore, the answer is **a. none**.
