\"36 cans of vegetables\" ___ c + t = 36 ___ c = 36 - t\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"80 cents for tomatoes and 40 cents for a can of corn, for a total cost of $20.80\" ___ 80t + 40c = 2080\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "substituting ___ 80t + 40(36 - t) = 2080\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "80t + 1440 - 40t = 2080\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "40t = 640 ___ t = 16
