The revenue for a company producing widgets is given by y = -20x2 - 50x + 200, where x is the price in dollars for each widget.

lisov135 [29]

Answer:

The price is x = $2.779

Step-by-step explanation:

From the question we are told that

The revenue is $y = - 20x^2 - 50 x + 200$

The cost of production is $y = 30 x - 10$

Generally at break even point the cost of production is equal to the revenue

$-20x^2 -50x + 200 = 30x-10$

=> $20x^2 +20 -210 = 0$

Using the quadratic formula to solve this equation we have that

x = $2.779
