<human>:  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?
<bot>: How many hats does fire chief Simpson have? ** Twice as many hats as fire chief Simpson has is 2 * 15 = <<2*15=30>>30 hats.
How many hats does fire chief Simpson have? ** 5 more than 30 hats is 30 + 5 = <<30+5=35>>35 hats.
How many hats does fire chief Simpson have? ** One less than 35 hats is 35 - 1 = <<35-1=34>>34 hats.
