The profit that the vendor makes per day by selling x pretzels is given by the function Upper P (x )equals negative 4 x squared plus 2 comma 400 x minus 400. Find the number of pretzels that must be sold to maximize profit.

The number of pretzels that must be sold to maximize profit is 300.

Step-by-step explanation:

The daily profit of selling x pretzels is given by the following equation:

Vertex of a quadratic function:

Suppose we have a quadratic function in the following format:

It's vertex is the point

In which

If a<0, the vertex is a maximum point, that is, the maximum value happens at , and it's value is

Find the number of pretzels that must be sold to maximize profit.

This is the x of the vertex.

We have that:

So

Then

The number of pretzels that must be sold to maximize profit is 300.

answer: 20

step-by-step explanation: subtract the minimum date value from the maximum data value to find the date range. in this casem the date range is 42 - 22 = 20

hope this ! : ) ~zane

1/3

step-by-step explanation:

to find this, you can divide 12 by 4 which is 3 or you can multiply 4 until you reach 12 (4x3=12). both should give you 3, meaning theres three times less bananas than there are oranges.
