Lizzy: Before he lost one, Policeman O'Brien had 5 more than twice as many hats as fire chief Simpson. If fire chief Simpson has 15 hats, how many hats does Policeman O'Brien now have?.
Me: Hmmm, let me think. I think this is the detailed solution:
Twice as many hats as fire chief Simpson has is 2 * 15 = 30 hats. 5 more than 30 hats is 30 + 5 = 35 hats. One less than 35 hats is 35 - 1 = 34 hats. Final answer: 34.
