Question 1172541: The weekly profit of your group’s home-made brownies in a box is modeled by the equation profit, P = - x2 + 120x - 28. The weekly profit P is dependent on the number of boxes of brownies x sold. If the break-even point is when P = 0, then how many boxes of brownies must your group sell in a week in order to break-even your profit? Answer by Solver92311(821) (Show Source):
The graph of your profit function is a concave down parabola, so the maximum profit is at the vertex of the parabola. The general equation for a parabola is:
The value of the independent variable at the vertex of the general parabola is .
Determine, by inspection, the values of and that are specific to your question and then calculate to find your answer.
