Answer:
Step-by-step explanation:
We have three people 
jamal = x (since im guessing hes the youngest)
wesley= x+1
John= x+2
the formula you would use is x+x+1+x+2=108
when you simplify that you get 3X+3=108
you subtract the 3 from 108 which leaves you with 3X=105
divide that by 3 which makes x=35
so 
jamal is 35
wesley is 36
john is 37
