To calculate your total earnings for a 7.5-hour shift on Saturday, we can follow these steps:

1. Find the Saturday hourly rate: You are paid an additional 25% on your base hourly rate. So, the hourly rate on Saturday is:

   $\text{Saturday rate} = \text{Base rate} + 25\% \times \text{Base rate}$

   $\text{Saturday rate} = 24.08 + (0.25 \times 24.08)$

   $\text{Saturday rate} = 24.08 + 6.02 = 30.10$

2. Calculate total earnings: Now, multiply the Saturday hourly rate by the number of hours worked (7.5 hours):

   $\text{Total earnings} = 30.10 \times 7.5 = 225.75$

So, your total earnings for a 7.5-hour shift on Saturday is $225.75.
