Area=length*width
let the sides perpendicular to the river be x
then the side parallel to the river is 4,700-2x
A(x)=x(4700-2x)
A(x)=4700x-2x^2
This a quadratic function with a=-2 and b=4700
thus
Maximum area occurs where x=-b/2a=-4700(-2*2)=1,175 ft
length=4700-2(1175)=2,350 ft

Answer:
I can't make out the second half of the problem, but I think that the answer is 3.35g + 0.72f = t
g = granola
f = flour
t = total
Answer:
f ^-1 (x) =7X/5 - 2/5
