Dan's Mobile Window Tinting tints car windows.
\n" ); document.write( " Dan has determined his company's weekly revenue and cost functions as follows:
\n" ); document.write( "R(w) = 37w + 8
\n" ); document.write( "C(w) = 27w + 688
\n" ); document.write( "where R(w) represents the weekly revenue in dollars from tinting w windows and C(w) represents the weekly cost in dollars to tint w windows.

\n" ); document.write( "Dan must tint at least ______ windows to break even or make a profit.
\n" ); document.write( ":
\n" ); document.write( "Break even point is when revenue = cost; R(w) = C(w); therfore
\n" ); document.write( "37w + 8 = 27w + 688
\n" ); document.write( "37w - 27w = 688 - 8
\n" ); document.write( "10w = 680
\n" ); document.write( "w = 680/10
\n" ); document.write( "w = 68 windows required to break even
\n" ); document.write( ";
\n" ); document.write( ":
\n" ); document.write( "see if this is true, find the actual $$ for each, should be equal
\n" ); document.write( "R(w) = 37(68) + 8
\n" ); document.write( "R(w) = 2516 + 8
\n" ); document.write( "R(w) = 2524

\n" ); document.write( "C(w) = 27(68) + 688
\n" ); document.write( "C(w) = 1836 = 688
\n" ); document.write( "C(w) = 2524
