Quizplus · Accepted Answer

To find the number of units manufactured at a cost of $7400, set $C(x) = 7400$ and solve the equation $x^2 - 50x + 5000 = 7400$. Simplifying gives $x^2 - 50x - 1400 = 0$. Solving this quadratic equation, the solutions are $x = 80$ and $x = -30$. Since the number of units cannot be negative, the answer is 80 units.
