Story Work Representative Of A Quadratic Equation

Influenza A virus subtype H5N1 toy manufacturer sells its products for $60/unit. The cost of manufacturing the production is obtained according to the equation B = x² + 10x. How many units of production must endure produced as well as sold inwards lodge to earn $600 profit!

Answer:
Profit = Income - Manufacturing cost
Profit = Selling cost x sum produced - Manufacturing cost

600 = 60x - (x² + 10x)
600 = 60x - x² - 10x
600 = - x² + 50x
0 = - x² + 50x - 600
0 = x² - 50x + 600
0 = (x - 30)(x - 20)

x₁ - xxx = 0
x₁ = 30

x₂- xx = 0
x₂ = 20

So to earn $600 net turn a profit should endure produced as well as sold equally many equally 30 units or 20 units.
