To calculate your Saturday earnings, we'll account for the 25% extra pay per hour and then multiply that by the hours worked. Here’s the step-by-step process:

1. Base hourly rate: $24.08
2. Saturday additional rate: 25% of $24.08 = $0.25 \times 24.08 = 6.02$
3. Saturday hourly rate: $24.08 + 6.02 = 30.10$ per hour
4. Total Saturday earnings for 7.5 hours: $30.10 \times 7.5 = 225.75$

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

1. What would your total earnings be for a full week if you worked 40 hours during the week and 7.5 hours on Saturday?
2. How much more do you earn on Saturdays compared to a regular day?
3. If your hourly rate increased by 10%, what would be your new Saturday rate?
4. What is the percentage increase in your weekly pay if you work a Saturday shift compared to a regular week?
5. How many hours would you need to work on Saturday to earn $300?

Tip: When dealing with percentages in wage calculations, always multiply the base by the percentage first, then add the result to the base rate.
