In this situation, the independent and dependent quantities can be identified as follows:
- Independent quantity: This is the quantity that you can control or choose, which in this case is the number of cars being washed.
- Dependent quantity: This quantity depends on the independent quantity, which here is the money raised from the car wash, as it will change based on the number of cars washed.
Given that the car wash charges $20 per car and they expect between 30 and 100 cars, we can summarize this as:
- The independent quantity (number of cars) can vary from 30 to 100.
- The dependent quantity (money raised) will be calculated based on the number of cars, resulting in amounts from $600 (30 cars x $20) to $2000 (100 cars x $20).
Thus, the reasonable domain and range values would be:
- Domain (number of cars): 30 to 100
- Range (money raised): $600 to $2000
Based on this analysis, the correct statement from your options is:
number of cars; money raised; 30 to 100 cars; $600 to $2000
