1 can = 3 hours
\n" ); document.write( "4.5 hours/day for a week is needed for 680 tvs\r
\n" ); document.write( "\n" ); document.write( "Find total number of hours needed first.\r
\n" ); document.write( "\n" ); document.write( "hours per day * days per week * number of tvs
\n" ); document.write( "4.5 * 7 * 680 = 21420\r
\n" ); document.write( "\n" ); document.write( "21420 is the total hours needed\r
\n" ); document.write( "\n" ); document.write( "take total hours and divide by 3 gives you total cans needed to be recycled.\r
\n" ); document.write( "\n" ); document.write( "21420/3 = 7140 is the total number of cans needed.\r
\n" ); document.write( "\n" ); document.write( "
