Begin with Roger Since he is paid once a month. You know he will receive only 12 checks per year.
Next multiply 12 * 2 = 24 for Adrianne.
Then take
24 (adrianne) - 12 (Roger) =
Which gives you 12 checks.
The amount they each make is irrelevant, since the question is only asking about the checks, not amount per check.
Your answer is
Arianne receives 12 more checks then Roger per year.
