MATH PUZZLE: Can you replace...

Mrs. Pete Monaghan came into the newsroom to pay for her husband's obituary. She was told by the kindly newsman that it was a dollar a word. Apologizing that she only had two dollars, she wrote this obituary: "Pete died."

"I remember ol' Pete, and he deserves more than two words," said the newsman. "I'll give you three more for free."

The widow thanked him and wrote, "Pete died. Boat for sale."
