You didn't specify how much is charged per ride to determine revenue...but we can just use a variable p for the price charged per ride...
r(x)=px, c(x)=15x+200
To break even, P, profit must equal zero and P(x)=r(x)-c(x)
P(x)=px-15x-200
P(x)=0 when x(p-15)-200=0
x=200/(p-15)
So the number of rides needed, x, can be found once you determine what is charged per ride. :D *note from even this partial answer that p must be greater than 15 or you will never break even.
Using derivatives, it is found that the slope of the line tangent to the graph of y at x = 1 is of 5.
The equation is:
The slope of the line tangent to the graph of y at x = 1 is 
.
Applying the quotient rule, we have that:
![y^{\prime}(x) = \frac{[9x^2]^{\prime}(x + 2) - [x + 2]^{\prime}(9x^2)}{(x + 2)^2}](https://tex.z-dn.net/?f=y%5E%7B%5Cprime%7D%28x%29%20%3D%20%5Cfrac%7B%5B9x%5E2%5D%5E%7B%5Cprime%7D%28x%20%2B%202%29%20-%20%5Bx%20%2B%202%5D%5E%7B%5Cprime%7D%289x%5E2%29%7D%7B%28x%20%2B%202%29%5E2%7D)
Then, when x = 1:
The slope of the line tangent to the graph of y at x = 1 is of 5.

Answer:
the answer is x=2 and y=3
Step-by-step explanation:
y=3 for x=2
y=3;x=2
x=2 and y=3
16,000
31,000
87,000
63,000
if the next digit is 5 or greater round up: if 4 or less leave the same.
