To calculate your earnings on a Saturday with the additional 25% per hour, follow these steps:

1. Base hourly rate: $24.08
2. Saturday additional pay: 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: $30.10 \times 7.5 = 225.75$

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

Here are 5 related questions for practice:

1. What would your total pay be if you worked 8 hours on a Saturday?
2. How much would you earn in a 5-day week working 8 hours each day (without extra Saturday pay)?
3. What would your total earnings be if you worked 6 hours on a Saturday and 40 hours from Monday to Friday?
4. If your pay increases by 10%, what would your new Saturday hourly rate be?
5. How much more do you earn on a Saturday shift compared to a regular weekday shift?

Tip: To calculate percentage increases, multiply the base amount by $1 + \text{percentage increase as a decimal}$.
