The total car wash earnings, \( y \), can be expressed as a function of the number of cars washed, \( x \), using the following equation:
\[ y = 9x \]
In this equation, \( 9 \) represents the price charged for each car wash, and \( x \) is the number of cars washed.
\[ y = 9x \]
In this equation, \( 9 \) represents the price charged for each car wash, and \( x \) is the number of cars washed.
