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

1. Base hourly rate: $24.08

2. Additional pay on Saturday: 25% of $24.08
   $25\% \text{ of } 24.08 = 0.25 \times 24.08 = 6.02$ Therefore, the new hourly rate on Saturday is: $24.08 + 6.02 = 30.10$

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

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