Answer 2

7

Explanation:

Jenny is 8 years older than twice her cousin Sue's age.

The 1st equation will be :

J = 8 + 2S ---------(1)

The sum of their ages is less than 32.

The 2nd equation will be :

J + S < 32 ----------------(2)

Now rearrange both equations :

8 + 2S + S < 32

3S < 32 - 8

3S < 24

S < 24/3

S < 8

S = 7

The age of Sue I think will be 7 years.
