Camila, and Camila is twice as old as Luna, what are the ages of the
three sisters?

Create an equation with only one variable.

Answer 1

9514 1404 393

Answer:

• Luna is 9
• Camila is 18
• Ava is 24

Explanation:

We can express all of the ages in terms of Luna's age. Letting L represent Luna's age, we have ...

• Luna's age: L
• Camila's age: 2L
• Ava's age: 2L +6

The total of their ages is then ...

L +2L +(2L+6) = 51 . . . . an equation with one variable

5L = 45

L = 9

Luna is 9, Camila is 18, and Ava is 24.
