### J. Ballard Math III Mr. Kirkland's Class

The Johnson twins were born twelve years after their older sister.

This year, the product of the three siblings ages is exactly 618 more than the sum of their ages.

How old are the twins?

Press the "Y=" button on your calculator. clear everything out thats in there. plug this equation into the "Y1" spot. Then press "Zoom 6".

The line on the x-axis is how old the twins are. So since the line falls on 6, the twins are 6 years old.
