Answer 1

Solve the following quadratic equation and we get

$14x - 0.05x²=960\\\\x² - 280x + 19200 = 0\\\\x =\dfrac{(280 ± \sqrt{280^2 - 4\times 19200}}{2}\\\\x = \dfrac{(280 ± 40)}{2}\\\\x = 120 ~or ~x = 160$

HENCE,

They need to sell $\pmb{\underline{120} }$or$\pmb{\underline{160} }$ cases to make 960 in revenue.

Answer 2

Answer:

• 120 or 160

Step-by-step explanation:

Solve the given quadratic equation:

• 960 = 14x - 0.05x²
• x² - 280x + 19200 = 0
• x = (280 ± $\sqrt{280^2 - 4*19200}$)/2
• x = (280 ± 40)/2
• x = 120 or x = 160
