For the largest area, half the fence is used parallel to the river, and the other half is used for the two ends of the rectangular space.
The dimensions are 475 m by 237.5 m.
_____
Let x represent the length along the river. Then the area (A) is found as
.. A = x*(950 -x)/2
This equation describes a parabola with its vertex (maximum) halfway between the zeros of x=0 and x=950. That is, the maximum area is achieved when half the fence is used parallel to the river.

We have the vertex (-4, -1), therefore we have:
So firstly, let's figure out the expression for a singular goody bag. Since there's 2 of each item, a single goody bag is going to be
Now since we have 7 friends who are all getting 1 goody bag, multiply the cost of the goody bag by 7, and our expression is . Now we can solve it from there.
Firstly, solve the multiplication inside the parentheses:
Now add up what's inside the parentheses:
Lastly, multiply and <u>your answer will be $56.56</u>
