You can put this solution on YOUR website!
Cost per person varies inversely with the number of travellers
\n" ); document.write( " C = k/N
\n" ); document.write( " (k is the constant of proportionality)
\n" ); document.write( "To find k put the known values into the formula
\n" ); document.write( " C = k/N
\n" ); document.write( " $22 = k/25
\n" ); document.write( " so k = 22*25
\n" ); document.write( " k = 550\r
\n" ); document.write( "\n" ); document.write( " Therefore your formula is:-
\n" ); document.write( " C = 550/N\r
\n" ); document.write( "\n" ); document.write( " To solve problem:\r
\n" ); document.write( "\n" ); document.write( " C = 550/N
\n" ); document.write( " C = 550/40
\n" ); document.write( " C = $13.75
\n" ); document.write( "Hope this helps
