To determine your Saturday earnings, we can follow these steps:

1. Calculate the additional pay rate for Saturdays: Since you are paid an additional 25% on Saturdays, the extra rate is: $24.08 \times 0.25 = 6.02$ So, your Saturday hourly rate is: $24.08 + 6.02 = 30.10 \text{ per hour}$

2. Calculate total earnings for a 7.5 hour shift: Multiply the Saturday rate by the number of hours worked: $30.10 \times 7.5 = 225.75$

Therefore, you earn $225.75 for a 7.5 hour shift on Saturday.
