Let $\"+b+\"$ = the cost per pound in dollars of bananas
\n" ); document.write( "Let $\"+t+\"$ = the cost per pound in dollars of tofu
\n" ); document.write( "given:
\n" ); document.write( "(1) $\"+2b+%2B+4t+=+6.4+\"$
\n" ); document.write( "(2) $\"+t+=+6b+\"$
\n" ); document.write( "-------------
\n" ); document.write( "Substitute (2) into (1)
\n" ); document.write( "(1) $\"+2b+%2B+4%2A%286b%29+=+6.4+\"$
\n" ); document.write( "(1) $\"+2b+%2B+24b+=+6.4+\"$
\n" ); document.write( "(1) $\"+26b+=+6.4+\"$
\n" ); document.write( "(1) $\"+b+=+.2462+\"$
\n" ); document.write( "and, since
\n" ); document.write( "(2) $\"+t+=+6b+\"$
\n" ); document.write( "(2) $\"+t+=+6%2A.2462+\"$
\n" ); document.write( "(2) $\"+t+=+1.4769+\"$
\n" ); document.write( "The bananas are $.25 / lb
\n" ); document.write( "The Tofu is $1.48 / lb
\n" ); document.write( "-------------------
\n" ); document.write( "(1) $\"+2b+%2B+4t+=+6.4+\"$
\n" ); document.write( "(1) $\"+2%2A.2462+%2B+4%2A1.4769+=+6.4+\"$
\n" ); document.write( "(1) $\"+.4924+%2B+5.9076+=+6.4+\"$
\n" ); document.write( "(1) $\"+6.4+=+6.4+\"$
\n" ); document.write( "OK \n" ); document.write( "
