Step-by-step explanation:

Given : Michelle is three times as old as Fiona. Fiona is twice as old as Madeline. Madeline is five years old.

To find : How old is Michelle?          

Solution :

Let the Michelle is x years old.

The Fiona is y years old.

The Madeline is z years old.

$y=2(5)$

$y=10$

Fiona is 10 years old.

Michelle is three times as old as Fiona.

$x=3(10)$

$x=30$

Michelle is 30 years old.

Therefore, Option D - 30 years old is correct.
