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

1. Base hourly rate: $24.08

2. Additional pay on Saturday: 25% of $24.08

   $0.25 \times 24.08 = 6.02$

3. Total hourly rate on Saturday:

   $24.08 + 6.02 = 30.10$

4. Total earnings for a 7.5-hour shift:

   $30.10 \times 7.5 = 225.75$

So, you would earn $225.75 for a 7.5-hour shift on Saturday.
