Lizzy: Amy, Jeremy, and Chris have a combined age of 132. Amy is 1/3 the age of Jeremy, and Chris is twice as old as Amy. How old is Jeremy?.
Me: Hmmm, let me think. I think this is the detailed solution:
Let x represent the age of Jeremy. Amy:(1 / 3)x. Chris:2(1 / 3)x = (2 / 3)x. Total:x + (1 / 3)x + (2 / 3)x = 132. 2x = 132. x = 66 years old. Final answer: 66.
