Troy has \( p \) peppermints. Riley has 4 fewer peppermints than Troy. Write an expression that shows how many peppermints Riley has.

Riley has \( p - 4 \) peppermints. Since Riley has 4 fewer than Troy, you simply subtract 4 from the total number of peppermints that Troy has, represented by \( p \). It's a straightforward way to express their relationship in quantities! For a little twist: if Troy were to give Riley 2 of his peppermints, you could easily rewrite the expressions to find out how many each would have after that. Troy would have \( p - 2 \) and Riley would have \( p - 4 + 2 \) (or \( p - 2 \)). Fun, right?
