Looks like it should be D since they spent 0.08 on tickets and get 1.92. Then shirts are $55 so we subtract this from the profit.

Mr. Jones' other friend Ms. O'Neill has "x" meters of fencing, what is the maximum area in square meters she can have?
Alexus [3.1K]

Answer:

Max\ Area = \frac{x^2}{16}

Step-by-step explanation:

Given

P = x ---- the perimeter of fencing

Required

The maximum area

Let

L \to Length

W \to Width

So, we have:

P = 2(L + W)

This gives:

2(L + W) = x

Divide by 2

L + W = \frac{x}{2}

Make L the subject

L = \frac{x}{2} - W

The area (A) of the fence is:

A = L * W

Substitute L = \frac{x}{2} - W

A = (\frac{x}{2} - W) * W

Open bracket

A = \frac{x}{2}W - W^2

Differentiate with respect to W

A' = \frac{x}{2} - 2W

Set to 0

\frac{x}{2} - 2W = 0

Solve for 2W

2W = \frac{x}{2}

Solve for W

W = \frac{x}{4}

Recall that:

L = \frac{x}{2} - W

L = \frac{x}{2} - \frac{x}{4}

L = \frac{2x- x}{4}

L = \frac{x}{4}

So, the maximum area is:

A = L * W

A = \frac{x}{4}*\frac{x}{4}

Max\ Area = \frac{x^2}{16}
