document.write( "Question 928310: If X units of a product costs C dollars to manufacture and earn revenue of R dollars, the value of X where the expression for C an R is called break- even quantity, the number of units that produce zero profit. Find the break even quantity when C = 16x+20000, and R= 18x.

c = 16x + 20000
\n" ); document.write( "r = 18x
\n" ); document.write( "---
\n" ); document.write( "at break even:
\n" ); document.write( "c = r
\n" ); document.write( "---
\n" ); document.write( "16x + 20000 = 18x
\n" ); document.write( "2x = 20000
\n" ); document.write( "x = 10000
