Answer:
A. $18
B. $200
C. 
Step-by-step explanation:
Function:
<u>Parts A and B:</u>
The price that generates the maximum profit is ate vertex of parabola. Find the coordinates of the vertex:
The price that generates the maximum profit is $18
The maximum profit is $200
<u>Part C:</u>
The company breaks even when the profit is positive. From the graph of the function you can see that the graph of the function is over p-axis for all , so the positive profit is for
In p=16 and p=20, the profit is 0 and when p<16 and p>20, there will be a loss.
Answer:
1 1/3
Step-by-step explanation:
you have to take away 2/3 and 1/4 and add the one and your answer is 1 1/3 and the bottom of the fraction stay the same
Let
x---------> represent the number of miles Troy's has driven
y--------> represent the amount of gas in Troy's truck
we know that
the equation that represents the amount of gas, y, in troy' s truck after driving a certain number of miles, x is
where
m is the slope---------> 
in this problem the slope is equal to 
it's negative because the tank is going to be consumed
assuming he starts with a full tank
substitute in the formula above
therefore
the answer is
the equation
