400cm
Step-by-step explanation:
As a practical equation, this one doesn't make much sense -- why would the profit per person have a term proportional to the number of people? Let's just go with it.
![18x + \dfrac{35}{x}](https://tex.z-dn.net/?f=18x%20%2B%20%5Cdfrac%7B35%7D%7Bx%7D)
![= \dfrac{18x^2}{x} + \dfrac{35}{x}](https://tex.z-dn.net/?f=%3D%20%5Cdfrac%7B18x%5E2%7D%7Bx%7D%20%2B%20%5Cdfrac%7B35%7D%7Bx%7D)
![= \dfrac{18x^2 + 35}{x}](https://tex.z-dn.net/?f=%3D%20%5Cdfrac%7B18x%5E2%20%2B%2035%7D%7Bx%7D)

35/x represents a portion of the profit that's 35/x per person, or a constant $35 per tour.
C.
l b +8 l = 6 (divided both side by 5)

you get answer choice c<span />
