Let $\"+g+\"$ = the price in cents of the grapefruit
\n" ); document.write( "Let $\"+b+\"$ = the price in cents of the ball
\n" ); document.write( "given:
\n" ); document.write( "(1) $\"+b+%2B+.07b+=+515+-+g+\"$
\n" ); document.write( "(2) $\"+.07b+=+18+\"$
\n" ); document.write( "--------------
\n" ); document.write( "(1) $\"+1.07b+=+515+-+g+\"$
\n" ); document.write( "(2) $\"+b+=+18%2F.07+\"$
\n" ); document.write( "(2) $\"+b+=+257.14+\"$
\n" ); document.write( "and
\n" ); document.write( "(1) $\"+1.07%2A257.14+=+515+-+g+\"$
\n" ); document.write( "(1) $\"+275.14+=+515+-+g+\"$
\n" ); document.write( "(1) $\"+g+=+515+-+275.14+\"$
\n" ); document.write( "(1) $\"+g+=+239.86+\"$
\n" ); document.write( "The grapefruit is $2.40
\n" ); document.write( "The ball is $2.57
\n" ); document.write( "check:
\n" ); document.write( " $\"+515+=+240+%2B+1.07%2A257+\"$
\n" ); document.write( " $\"+515+=+240+%2B+275+\"$
\n" ); document.write( " $\"+515+=+515+\"$
\n" ); document.write( "OK
