    Still dont trust her, but there is allways the chance she changes her ways – should she be an agent after Ray.

    And she quickly recognizes Ray’s sneaky math teaching.

    That word problem needs a clarification – do you count both the year she turned 10 and the year she turned 32? If so, the answer is 23×12. If you don’t count both those years, it would be 22×12. The problem of partial years is inherent in any word problem involving ages, anniversaries, or time that has to be represented as a whole number. For the whole year we say you were one year old, you were actually more than one year old. For this problem, the whole second year she was collecting cards, she actually had more than 12 cards.

    It would more clear if it read like this: When Lynn was 10 years old, she collected 12 baseball cards. When she was 11 years old, she collected another 12. She has continued to collect 12 baseball cards a year for her whole life. This year she turned 32 years old, and she has just collected another 12 cards. How many cards does she have? That clearly means the answer is 23×12.
