Question

Angela is twice as old as Brent. Brent is two and a half times as old as Casey. Casey is 5 years old. How old is Angela?

Answer 1

Let's list some equations :)

We know Casey's age already: c = 5

Brent's age: b = 2.5c

Angela: a = 2b

For Brent's equation, we can substitute the value of 5 in for c ( since c equals 5). 2.5*5 = 12.5, so Brent is 12 and a half years old (12.5).

Since we now know that b = 12.5, we can solve Angela's age too. 2*12.5 = 25. Angela is 25 years old.

Hope this helps! Have a nice day :)

Answer 2

Casey = 5 years old

Brent is two and a half times as old as Casey:
Brent = 2.5(5) = 12.5 years old

Angela is twice as old as Brent.
Angela = 2(12.5) = 25 years old

Angela is 25 years old
