It is given that the cost function C(x) is given by
Also, the revenue function R(x) is given by
The break even point can be determined by equating the cost function and the revenue function.
Thus, we have,
Subtracting both sides by , we get,
Dividing both sides by , we have,
Thus, it takes 12 units to be sold to break even.
Hence, the number of units of x that must be sold to break even is 12 units.
