Answer: Okay so I got a straight line when I graphed it, maybe put the other function and I can find the point of intersection
Step-by-step explanation:
Answer:
Your wrong, it’s B.
X axis = Number of Bottles of water sold
Y axis = Number of dollars collected
So, (x,y)
That means, (Number of Bottles of water sold,Number of dollars collected)
Finally, (10,20) means he sold 10 bottles of water for $20.
Hope that helped!

Check the picture below.
so if we simply subtract the strip area with the pond and the area of the pond only, what's leftover is the area of the strip alone, so
![\stackrel{\textit{area of the grass \underline{with} pond}}{(15+2x)(18+2x)}-\stackrel{\textit{area of the pond}}{(15)(18)}=\stackrel{\textit{their difference}}{232} \\\\\\ 270+30x+16x+4x^2-270=232\implies 46x+4x^2=232 \\\\\\ 23x+2x^2=116\implies 2x^2+23x-116=0](https://tex.z-dn.net/?f=%5Cstackrel%7B%5Ctextit%7Barea%20of%20the%20grass%20%5Cunderline%7Bwith%7D%20pond%7D%7D%7B%2815%2B2x%29%2818%2B2x%29%7D-%5Cstackrel%7B%5Ctextit%7Barea%20of%20the%20pond%7D%7D%7B%2815%29%2818%29%7D%3D%5Cstackrel%7B%5Ctextit%7Btheir%20difference%7D%7D%7B232%7D%20%5C%5C%5C%5C%5C%5C%20270%2B30x%2B16x%2B4x%5E2-270%3D232%5Cimplies%2046x%2B4x%5E2%3D232%20%5C%5C%5C%5C%5C%5C%2023x%2B2x%5E2%3D116%5Cimplies%202x%5E2%2B23x-116%3D0)

now, the negative root will simply yield a negative value, which is not applicable here, so we'll only use the positive root, since it's the only feasible one for the phenomena
