The cost, C, of a manufacturing and selling x units of a product is C = 23x+73, and the corresponding revenue, R, is= x^235. Find the breakeven value of x?
A. 4
B. 31
C. 31 and 4
D. 27

Breakeven point: C = R
23x + 73 = x^2  35
Set equation equal to 0:
0 = x^2  23x  108
Try to factor:
0 = (x  27)(x + 4)
Set each factor equal to 0:
x  27 = 0
x + 4 = 0
Possible solutions: 4, 27
Throw out the negative number and you will have your answer!
I hope this helps.
