\"x\"= weekly costs (labor + materials + overhead)
\n" ); document.write( "\"0.3x\"= 30% of weekly costs = direct labor costs
\n" ); document.write( "\"2%2A%280.3x%29%2B2000=0.6x%2B2000\"= 2,000 more than twice \"0.3x\" = weekly raw materials cost
\n" ); document.write( "\"0.2%2A%280.3x%29=0.06x\"= 20% of \"0.3x\" = weekly overhead costs
\n" ); document.write( "
\n" ); document.write( "\"x=0.3x%2B%280.6x%2B2000%29%2B0.06x\"
\n" ); document.write( "\"x=0.3x%2B0.6x%2B2000%2B0.06x\"
\n" ); document.write( "\"x=0.3x%2B0.6x%2B0.06x%2B2000\"
\n" ); document.write( "\"x=%280.3x%2B0.6x%2B0.06x%29%2B2000\"
\n" ); document.write( "\"x=%280.3%2B0.6%2B0.06%29x%2B2000\"
\n" ); document.write( "\"x=0.96x%2B2000\"
\n" ); document.write( "\"x-0.96x=0.96x%2B2000-0.96x\"
\n" ); document.write( "\"%281-0.96%29x=2000\"
\n" ); document.write( "\"0.04x=2000\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"0.04x%2F0.04=2000%2F0.04\"
\n" ); document.write( "\"highlight%28x=50000%29\"
\n" ); document.write( "Total wekly costs are $50,000.
\n" ); document.write( "30% of that is direct labor costs ($15,000=$50,000 X 0.30).
\n" ); document.write( "Material cost $32,000 per week ($2,000 more than twice the amount of direct labor costs above).
\n" ); document.write( "Weekly overhead costs are $3,000 (20% of direct labor costs).
\n" ); document.write( "It adds up;
\n" ); document.write( "$15,000+$32,000+$3,000=$50,000
\n" ); document.write( "
