A retailer who sells backpacks estimates that by selling them for x dollars each, she will be able to sell 100−x backpacks each
zvonat [6]

Answer:

x = 50

R = $2500

Step-by-step explanation:

Given in the question a quadratic equation,

−x² + 100x

To find the selling price, x, which will give highest revenue, y, we will find maximum value of parabola curve −x² + 100x

The value of -b/2a tells you the value x of the vertex of the function

−x² + 100x

here a = -1

        b = 100

Selling price = -(100)/2(-1)

                    =   50

 

R = −(50)² + 100(50)

  = 2500

max said that 36594 is less than 5980 because 3 is less then 5 describe max's error and give the correct answer
Verizon [17]
He was wrong because, although three is greater than five, the value of the three is in the ten thousands place, while the five is in the thousands place. Therefore, the correct answer would be that 36594 is greater than 5980.
