In 8 min, Shelly stocks \"+23%2A8+=+184+\" cans
\n" ); document.write( "There are \"+500+-+184+=+316+\" cans left to stock
\n" ); document.write( "—————-
\n" ); document.write( "Let \"+t+\" = time for them to finish working
\n" ); document.write( "Add their rates of working to get their rate working together
\n" ); document.write( "\"+17+%2B+23+=+316%2Ft+\"
\n" ); document.write( "\"+40+=+316%2Ft+\"
\n" ); document.write( "\"+t+=+7.9+\" min
\n" ); document.write( "It takes them 7.9 min to stock the rest of the cans\r
