To represent the amount of money remaining on the prepaid card after purchasing \( x \) movie tickets, we can define the function \( m(x) \).
Starting with the initial value of the card, which is $180, we subtract the total cost of the movie tickets purchased. Since each movie ticket costs $12, the total cost for \( x \) tickets would be \( 12x \).
Thus, the function can be expressed as:
\[
m(x) = 180 - 12x
\]
This function \( m(x) \) gives the amount of money remaining on the card after buying \( x \) movie tickets.
