The profit, in dollars, of a small business can be modeled by the function P(x)=0.3x^2+7x-40, where c is the number of units sol
ra1l [238]

Answer:

The correct answer is 10 units.

Step-by-step explanation:

Profit function of a small business is given by P(x) = 0.3x^{2} + 7x - 40, where x is the number of units sold.

The small business intend to make a profit of $60.

To find out the number of units the business has to sell in order to have a profit of $60 is given by,

P(x) = 0.3x^{2} + 7x - 40 = 60

⇒ 0.3x^{2} + 7x - 100 = 0

⇒ 3x^{2} + 70x - 1000 = 0

⇒ x = -70 ± \sqrt{(70)^{2} + 12000} × \frac{1}{6}

⇒ x = -70 ± 130 × \frac{1}{6}

⇒ x = 10 or -\frac{200}{6}

Quantity sold cannot be negative giving us the value of x as 10 units.
