Answer:
$68
Step-by-step explanation:
We have been given the demand equation for Turbos as , where q is the number of buggies the company can sell in a month if the price is $p per buggy.
Let us find revenue function by multiplying price of p units by demand function as:
Revenue function:
Since revenue function is a downward opening parabola, so its maximum point will be vertex.
Let us find x-coordinate of vertex using formula .
The maximum revenue would be the y-coordinate of vertex.
Let us substitute in revenue formula.
Therefore, the company should sell each buggy for $68 to get the maximum revenue of $18,496.
