Which can be represented using the product 50 × -5? 

Question 3 options:

A submarine rising by 50 feet each hour for 5 hours 


Earning $50 a month for 5 months 


An airplane losing altitude by 5 feet each second for 50 seconds 


Saving $5 each day for 50 days 

The correct representation of the product $ 50 \times -5 $ refers to a scenario where there is a *loss* or decrease (represented by the negative sign). Thus, we are looking for a situation that describes a consistent loss or decrease over time.

Let's evaluate the options:

1. **A submarine rising by 50 feet each hour for 5 hours**:  
   This represents a *positive* change (rising), so it cannot be represented by a negative product like $ 50 \times -5 $.

2. **Earning $50 a month for 5 months**:  
   Earning money is a *positive* change, so this also cannot be represented by $ 50 \times -5 $.

3. **An airplane losing altitude by 5 feet each second for 50 seconds**:  
   This represents a *negative* change (losing altitude), and the amount is decreasing by 5 feet each second for 50 seconds. This fits the interpretation of $ 50 \times -5 $ (since the altitude decreases by $ 5 $ feet each second, the total loss in altitude is $ 50 \times -5 $).

4. **Saving $5 each day for 50 days**:  
   Saving money represents a *positive* change (increasing savings), so this cannot be represented by $ 50 \times -5 $.

### Correct answer:  
**An airplane losing altitude by 5 feet each second for 50 seconds**.
