Answer:
Price that generates maximum profit= $21.50
Maximum profit = $980
Explanation:
To find the price that generates the maximum profit, we need to find the maximum point of the function $f(p)$. The maximum point of a quadratic function is located at the vertex of the parabola.
The vertex of a parabola can be found using the formula
, where a and b are the coefficients of the x² and x terms in the quadratic equation, respectively.
In the case of the function f(p),
Comparing with f(p) = ax² + bx + c,
we get a=-80 and b=3440 and c = -36,000.
Substituting these values into the formula, we get:

This means that the maximum profit is generated when the price per frame is $21.50.
We can also find the maximum profit by evaluating the function at its vertex.
Evaluating f(p) at p=21.50, we get:
f(21.50)=-80(21.50)²+3440(21.50)-36,000
= -80 × 462.25 + 73960 - 36,000
= −36980 + 73960 - 36,000
= 980
Therefore, the maximum profit is $980 and it is generated when the price per frame is $21.50.
