The number of pretzels that must be sold to maximize the profit is 400.

<h3>What is the number of pretzels to be sold in the quadratic equation?</h3>

The number of pretzels to be sold can be determined by taking the derivative of the quadratic equation.

Given that:

P(x) = -4x^2+3200x-100

P'(x) = -8x + 3200

P''(x) = -8

At the critical point;

P'(x) = 0

Thus;

8x = 3200

x = 3200/8

x = 400

P''(400) = -8

P'' (400) < 0

Therefore, at x = 400, P(x) will be maximum.

Luda [366]

Answer:

The correct option is option B. It has one solution, and it's x=-3

Step-by-step explanation:

We have the following system of equations:

5x+7 = 2y                        (1)

y-9x=23                            (2)

Step 1: Solve for 'y' in equation (2):

y-9x = 23

y = 9x + 23

Step 2: Substitute in equation (1):

5x + 7 = 2y

5x + 7 = 2(9x + 23)

5x + 7 = 18x + 46

Step 3: Solve for x:

7 - 46 = 18x - 5x

-39 = 13x

x= -3

So the correct option is option B. It has one solution, and it's x=-3
