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 reasonable domain and range values.

a: number of cars; money raised; 30 to 100 cars; $600 to $2000
b: money raised; number of cars; 30 to 100 cars; $600 to $2000
c: number of cars; money raised; $600 to $2000; 30 to 100 cars
d: money raised; number of cars; $600 to $2000; 30 to 100 cars

Option A: number of cars; money raised; 30 to 100 cars; $600 to $2000 is the right option.

Step-by-step explanation:

In the given question number of cars represents the independent variable while money raised represents independent variable.

Dependent variable depend on other entity while independent variable does not.

Here cars are independent and money is dependent as money is dependent on the number of cars.

The charge per car is $20.

So, for 30 cars, charges will be = dollars

And for 100 cars, charges will be = dollars

Option A: number of cars; money raised; 30 to 100 cars; $600 to $2000 is the right option.

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
