call the set-up fee $\"s\"$
\n" ); document.write( "Call the hourly fee $\"h\"$
\n" ); document.write( "total cost = (hourly fee)x(hrs) + set-up fee
\n" ); document.write( "For Gina:
\n" ); document.write( " $\"230+=+h%2A5+%2B+s\"$
\n" ); document.write( "(1) $\"5h+%2B+s+=+230\"$
\n" ); document.write( "For Lori:
\n" ); document.write( " $\"125+=+h%2A2+%2B+s\"$
\n" ); document.write( "(2) $\"2h+%2B+s+=+125\"$
\n" ); document.write( "Subtract (2) from (1)
\n" ); document.write( "(1) $\"5h+%2B+s+=+230\"$
\n" ); document.write( "(2) $\"-2h+-+s+=+-125\"$
\n" ); document.write( " $\"3h+=+105\"$
\n" ); document.write( " $\"h+=+35\"$
\n" ); document.write( "The hourly rental fee is $35 \n" ); document.write( "
