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

1. Base hourly rate: $24.08

2. Additional pay rate: 25% of $24.08 = $0.25 \times 24.08 = 6.02$

3. Saturday hourly rate: $24.08 + 6.02 = 30.10$

4. Total earnings for 7.5 hours: $30.10 \times 7.5 = 225.75$

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