Answer:
D
Step-by-step explanation:
Use the distance formula to find all of the sides.
Then add them together
In the figure we have the graphic of this equation. So, the vertex is the maximum of this function. This point means that the maximum <span>daily profit from soccer balls is:
</span>

<span>
And this happens when the </span><span>selling price of each soccer ball is:
</span>

<span>
So if you want to get the best daily profit, this is the price you must sell each soccer ball.</span>
If

then the derivative is

Critical points occur where
. This happens for



In the first case, we find

In the second,

So all the critical points occur at multiples of
, or
. (This includes all the even multiples of
.)
