Which of these pairs of costs and revenues could a company have if it's at its<br> break-even point?
sertanlavr [38]

Answer:

At break even cost = revenue

Step-by-step explanation:

A company is said to be at break even if the cost of producing an item is equal to the revenue generated from the sell of that item, that means there is no loss or gain.

If the cost function C(x) = 200 + 10x and the revenue function R(x) = 60x - x², where x is the amount of items produced. At break even, R(x) = C(x)

60x - x² = 200 + 10x

x² - 60x + 10x + 200 = 0

x² - 50 x + 200 = 0

x = 46 or x = 4 is the break even point

Perpendicular lines have slopes that are opposite reciprocals. It means that if we have 8, then its opposite reciprocal would be -1/8.

Hope this helps!
