It is given in the question that,
The French club is holding a car wash fundraiser. They are going to charge $10 per car, and expect between 50 and 75 cars.
The cost depends on the number of cars washed .
So number of cars is the independent quantity and cost is the dependent quantity .
And here, let, y represents the cost and let x represents the number of cars.
[tex]y= 10x[/tex]
So the domain is 50 to 75 cars.
And when x=50 and 75, value of y is
[tex]y=10*50 , y=10*75
\\
y= 500, y=750[/tex]
And the range is $500 to $750 .
So the correct option is B
