The end of a hose was resting on the ground, pointing up an angle. Sal measured the path of the water coming out of the hose and
found that it could be modeled using the equation f(x) = –0.3x2 + 2x, where f(x) is the height of the path of the water above the ground, in feet, and x is the horizontal distance of the path of the water from the end of the hose, in feet.
When the water was 4 feet from the end of the hose, what was its height above the ground?
A. 3.2 feet
B. 4.8 feet
C. 5.6 feet
D. 6.8 feet

Answer:
Yes, Cam's costs proportional to the number of votes he receives.
Step-by-step explanation:
It is given that Cam is a corrupt politician. Nobody votes for him except those he pays to do so. It costs Cam exactly $100 to buy each vote.
Let the number of votes he get be x.
Then the total cost of Cam is
... (1)
Where, C is Cam's costs and x is number of votes he receives.
Two variables are proportional to each other if
... (2)
Where k is constant of proportionality.
Since equation (1) and (2) and similar and the constant of proportionality is 100, therefore we say that Cam's costs proportional to the number of votes he receives.
