Given the function of the profit P(x)


P(x)=150x-x^2

Part (b):

We will find the number of cases of pies to maximize the profit.

the given function has a negative leading coefficient and from part (a) the function will be zero when x = 0 and x = 150

Form the symmetry of the quadratic function, the maximum point will be in the middle between x = 0, and x = 150

so, the middle point will be as follows:


x=(0+150)/(2)=75

So, the maximum profit will be at x = 75

Substitute x = 75 into P(x)


P(75)=150*75-75^2=5625

So, the answer will be:

The number of cases of pies to maximize the profit = 75

The maximum profit = $5625
