Answer 1

Let's denote Babs' age as \( x \). Since Julia is five years older than Babs, we can represent Julia's age as \( x + 5 \).

According to the problem, their ages add up to 31: \[ x + (x + 5) = 31 \] Simplifying this equation: \[ 2x + 5 = 31 \] Subtracting 5 from both sides: \[ 2x = 26 \] Dividing both sides by 2: \[ x = 13 \]

So, Babs is 13 years old.

The correct response is: B 13
