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

1. Base hourly rate: $24.08
2. Additional pay on Saturday: 25% of the base rate $25\% \text{ of } 24.08 = 0.25 \times 24.08 = 6.02$
3. Saturday hourly rate: Add the additional pay to the base rate: $24.08 + 6.02 = 30.10$
4. Total earnings for 7.5 hours: $7.5 \times 30.10 = 225.75$

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

1. How much would you earn if you worked an 8-hour shift on Saturday?
2. What would your earnings be for a 10-hour shift during the week?
3. How much would you earn if your hourly rate was increased by 5%?
4. How would your earnings change if the Saturday pay increase was 30% instead of 25%?
5. What would your total weekly earnings be if you worked 40 hours during the week and 7.5 hours on Saturday?

Tip: When calculating percentage increases, always multiply the percentage (as a decimal) by the original amount to find the added value.
