Find the rate at which each can wrap gifts.
\n" ); document.write( "Ric does 38 in 4 hours, so ric can do \"38%2F4+=+9.5\" per hour
\n" ); document.write( "Vic does 27 in 3 hours, so vic can do \"27%2F3+=+9\" per hour
\n" ); document.write( "Together they can do \"9.5+%2B+9+=+18.5\" per hour\r
\n" ); document.write( "\n" ); document.write( "So how long does it take to wrap 37??\r
\n" ); document.write( "\n" ); document.write( "\"37+=+18.5+%2A+hours\"
\n" ); document.write( "\"37%2F18.5+=+hours\"
\n" ); document.write( "\"2+=+hours\"\r
\n" ); document.write( "\n" ); document.write( "2 hours
\n" ); document.write( "
