To calculate how much you earn for a 7.5-hour shift on Saturday, given your base hourly rate of $24.08 and the additional 25% pay on Saturdays, follow these steps:

1. Base hourly rate: $24.08
2. Saturday additional pay: 25% of $24.08 = $0.25 \times 24.08 = 6.02$

So, your total hourly rate on Saturday is: $24.08 + 6.02 = 30.10 \text{ per hour}$

3. Total earnings for a 7.5-hour shift: $30.10 \times 7.5 = 225.75$

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