<PRE><B>Question 768921</B>
Lauren is twice as old as her sister, Sue. The sum of their ages is 24. How old are the sisters ?


Let the age of Sue be n

Let the age of Lauren be 2n

Therefore:

n + 2n = 24

n + 2n = 3n

3n = 24

Divide each side by 3

3n/3 = 24/3

n = 8

2n = 2 * 8 = 16



Answer:

Sue is 8 years old and Lauren is 16 years old.
