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.

So the domain is 50 to 75 cars.
And when x=50 and 75, value of y is

And the range is $500 to $750 .
So the correct option is B
(2,-2)
(7,8)
-2-8 = -10
——. ——-
2-7. -5
-10/5 = 2/1
2/1 =
2
Slope is 2
Answer:
Correct answer is (c). 5
Step-by-step explanation:
It is important to note that solving problem requires techniques and intelligent people most especially when problem are complex or hard in nature. It is therefore important to ensure the numbers of problem solving experts should not be undersized than required to avoid over burden them and should not be too large to avoid conflict in their individual resolutions. Hence, most scientific reports state that problem solving experts should be within 3 to 5 members and as for this question, the optimum is 5 members.
