Question

Walking through the word problem please.

Answer 1

I think I would start out with this equation.

3x+4y=800

Answer 2

Well I have solved A) and B) portion of the problem. I need to solve for both X and Y of the problem though to find C)

Answer 3

A) \[\frac{ 800-3x }{ 4 }\]

B) \[\frac{ x(800-3x) }{ 4 }\]

C) States to find the dimensions that maxamize the enclosed area.

X=

Y=

Answer 4

@wio

Answer 5

So I know how to start it.

X(800-3x)/4

Needs to be evaluated. The problem is I am not sure if I am getting the right answer.

\[200x-\frac{ 3x^2 }{ 4 }\]

Answer 6

If I am right I would proceed plugging in the numbers into

\[-\frac{ b }{ 2(a) }\]

The only problem is I am not sure how to plug it in with that fraction hanging there

is a 200, and b 3/4?
