Suppose a casual relief teacher is paid $67.20 per hour. The rate of pay is also applied on a pro rata basis for part of an hour. Set up an equation that relates the total amount of pay (y) and the number of hours worked (x)

To set up an equation that relates the total amount of pay (y) and the number of hours worked (x) for a casual relief teacher who is paid $67.20 per hour, we can use the following equation: y = 67.20x In this equation, "y" represents the total amount of pay, "67.20" represents the rate of pay per hour, and "x" represents the number of hours worked. This equation states that the total amount of pay (y) is equal to the rate of pay per hour ($67.20) multiplied by the number of hours worked (x).
