\n" ); document.write( ".
\n" ); document.write( "Let T = amount Tim paid
\n" ); document.write( "T-3 = amount Bob paid
\n" ); document.write( ".
\n" ); document.write( "From: \"Together they spent $7.80\" we get our equation:
\n" ); document.write( "T + (T-3) = 7.80
\n" ); document.write( "2T - 3 = 7.80
\n" ); document.write( "2T = 10.80
\n" ); document.write( "T = 5.40 (amount Tim paid)
\n" ); document.write( ".
\n" ); document.write( "amount Bob paid:
\n" ); document.write( "T-3 = 5.40-3 = $2.40\r
