The expression \( 60 - 5x \) represents the number of tickets Lacey has left after going on \( x \) rides. In this expression:
- The number \( 60 \) represents the total number of tickets Lacey initially bought.
- The \( 5x \) part indicates that each ride costs \( 5 \) tickets, and for \( x \) rides, she will use \( 5x \) tickets.
Thus, Lacey bought 60 tickets and each ride needs 5 tickets.
