A corporation pays 1/2 of the health insurance premium and an additional $200 a month toward other health benefits, such as dental insurance. The total benefit package is $450 a month. How much is the health insurance premium each month? 2. Jack is three times as old as Jill. Ten years ago, Jack was five times as old as Jill. How old are Jack and Jill now?
