Joe's age is three times Aaron's age and Aaron is six years older than Christina. If the sum of their ages is 99, what is Christina's age? Joe's age? Aaron's age?
Joe's age is three times Aaron's age and Aaron is six years older than Christina. If the sum of their ages is 99, what is Christina's age? Joe's age? Aaron's age?
Let Christina's age=C
Aaron's age=C+6
Joe's age =3[C+6]
C+C+6+3[C+6] =99
2C+6+3C+18 =99
5C=99-6-18
5C=75 divide both sides by 5
C=75/5
C=15 years-Christina's age
15+6=21 years- Aaron's age
3 x 21=63 years-Joe's age
