Answer:
The maximum profit will be: $605.125
Explanation:
Given the function

The given equation is a quadratic function. It represents Parabola. The parabola opens down because of the negative leading coefficient (-2).
Thus, the maximum profit would be computed at the vertex of the graph.
Thus, we have to determine the value of y when x is the line of symmetry.
We can find this by the equation
x = -b/2a
where a = -2, b = 105
x = -105 / 2(-2)
x = -105 / -4
x = 105/4
x = 26.25
Now, putting x = 26.25 in the original function to find the value of 'y'.





Therefore, the maximum profit will be: $605.125
