To calculate the total earnings for a 7.5-hour shift on a Saturday with an additional 25% pay per hour, we can follow these steps:

1. Find the additional pay per hour on Saturdays:

   Since the additional pay is 25% of the base hourly rate, we calculate it as: $\text{Additional Pay per Hour} = 0.25 \times 24.08 = 6.02$

2. Determine the total hourly rate on Saturdays:

   Add the additional pay to the base hourly rate: $\text{Total Hourly Rate on Saturday} = 24.08 + 6.02 = 30.10$

3. Calculate the total earnings for a 7.5-hour shift:

   Multiply the total hourly rate by the number of hours worked: $\text{Total Earnings} = 30.10 \times 7.5 = 225.75$

Final Answer:

Your total earnings for a 7.5-hour shift on Saturday would be $225.75.
