Q: If a student consistently gets only 5 hours of sleep per night for a week, what is the total sleep debt accumulated by the end of the week, assuming the recommended amount is 8 hours per night? Use the formula $$\text{Sleep Debt} = (\text{Recommended Hours} - \text{Actual Hours}) \times \text{Number of Days}.$$

$$\text{Sleep Debt} = (8 - 5) \times 7 = 21$$ hours

Q: If an adult (26-64 years old) sleeps 6 hours per night for 5 nights, how much sleep debt do they accumulate, based on the recommended 7-9 hours per night? Use the lower end of the recommendation for calculation: $$\text{Sleep Debt} = (7 - 6) \times 5.$$

$$\text{Sleep Debt} = 5$$ hours
