document.write( "a) Write a linear system to represent this problem. Remember to define your variables \r\n" );
document.write( "\r\n" );
document.write( "With number of lawns to be mowed being x, we get revenue EQUATION as: R(x) = 10x \r\n" );
document.write( "                                                    Cost EQUATION as: C(x) = x + 450\r\n" );
document.write( "These are the required equations for your system.\r\n" );
document.write( "\r\n" );
document.write( "As you may know, Profit = Revenue - Cost. So, in this case, Profit = R(x) - C(x)\r\n" );
document.write( "                                                            Profit = 10x - (x + 450) = 10x - x - 450 = 9x - 450\r\n" );
document.write( "\r\n" );
document.write( "And, BREAK-EVEN units occur when R(x) = C(x), or in this case, 10x = x + 450
