Question

The French club is holding a car wash fundraiser. They are going to charge $20 per car , and expect between 30 and 100 cars. Identify the independent and dependent quantity in the situation, and find a reasonable domain and range values

Answer 1

Independent variable = number of cars with domain 30 to 100 cars
Dependent variable = money raised with range $600 to $2000

Answer 2

Answer: Independent variable → number of cars

Dependent variable → money raised

Domain →30 to 100 cars

Range → $600 to $2000

Explanation:

The independent variable here is the number of cars and the money raised by the club is dependent on the number of cars sold.

We know that the domain is the set of values of the independent variable from the least to maximum.

Since, they expect between 30 and 100 cars.

Therefore, the reasonable domain= 30 to 100 cars

The range is the set of values of the dependent variable, it is generally from the least to maximum.

The least amount they earn =
`30*20=\$600`

The maximum amount they earn =
`100*20=\$2000`

Therefore, Range = $600 to $2000
