Answer:
- 160 ft (out from the river)
- 320 ft (parallel to the river)
Step-by-step explanation:
Let x represent the length of fence parallel to the river. Then the dimension of perpendicular to the river will be half the remaining fence: (640-x)/2. The total area will be ...
A = x(640-x)/2
This is the equation of a parabola that opens downward. It has zeros at x=0 and x=640, so its axis of symmetry is x = (0+640)/2 = 320. That is, the peak of the area curve is found when x=320.
The dimensions of the garden with the largest area are 160 ft wide by 320 ft long, where the long side is the river side.

I feel like the answer is
10h = 110
although it's so simple that I'm not even sure it would be considered an equation.
I got the answer because she works, in total, 10 hours a week. She makes $130 a week, but since $20 comes from the dog walking, you have to do 130 minus 20 which is 110. That's what I did anyway.
