The smallest amout that the school should charge is $4.70.
Step-by-step explanation:
p = -200t2 + 3600t - 6400
p = -200 x 4.7 x 2 + 3600 x 4.7 - 6400
p = -1880 + 16920 - 6400
p = 15120 - 6400
p = 8720
Let x denote the length of the side of the garden which is covered fenced by a shed, and

be the width of the garden.
The perimeter of a rectangle is given by 2(length + width)
i.e.
which gives:

For the area to be maximum, the differentiation of A with respect to x must be equal to 0.
i.e.

Therefore, the maximum area of the garden enclosed is given by
Answer:
