To calculate your earnings for a 7.5-hour shift on Saturday, you need to account for the additional 25% pay rate on top of your base hourly rate. Here's how you do it:

1. Base hourly rate: $24.08

2. Additional pay rate on Saturdays: 25% of $24.08

   $\text{Additional pay} = 0.25 \times 24.08 = 6.02$

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

4. Total earnings for 7.5 hours:

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

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