1. **State the problem:** We need to identify which scenarios can be described by the number $-300$. 2. **Understand the meaning of negative numbers:** Negative numbers often represent a decrease, a loss, or a position below a reference point (like sea level or starting elevation). 3. **Analyze each scenario:** - A) The rhinoceros weighed 1,230 pounds and now weighs 1,530 pounds. The weight increased by $1530 - 1230 = 300$, which is positive, so this is +300, not -300. - B) The town was 300 feet above sea level. This is a positive elevation, so it corresponds to +300, not -300. - C) The scuba diver swam to a depth of 300 yards. Depth below the surface is often represented as negative, so this can be $-300$ yards. - D) The customer had 650 in the account and now has 350. The change is $350 - 650 = -300$, a decrease of 300, so this matches $-300$. - E) The hiker walked from 1,100 feet to 800 feet. The change is $800 - 1100 = -300$, a decrease of 300 feet, so this matches $-300$. 4. **Final answer:** Scenarios C, D, and E describe the number $-300$. **Answer:** C, D, E
