\n" ); document.write( " $\"M+=+2J\"$ Mary’s hourly wage is twice that of John’s

\n" ); document.write( " $\"D%2BJ+=+60\"$ John’s and Dennis’ hourly wages together total $60

\n" ); document.write( " $\"J+=+3D\"$ Dennis earns 1/3 of John’s rate (i.e., John earns 3 times as much as Dennis)

\n" ); document.write( "Solving should be relatively easy.

\n" ); document.write( "Use the third equation to substitute in the second equation to solve for D; then use the third equation to solve for J; then use the first equation to solve for M. \n" ); document.write( "
