Question 261291
Don is twice as old as Irene; Ed is 16 years older than Irene. The sum of all three of their ages is 60 years. Find the age of each person.

D Don, I Irene, E Ed

D=2I
E=I+16
D+I+E=60

2I + I + I + 16 = 60
4I + 16 = 60
4I = 44
I = 11 which is Irene's age

so if Irene is 11, then Don is 22 and Ed is 27
