Let \"1.5a\" = cost of the 1st lesson
\n" ); document.write( "Then \"a\" = cost of each of the next 7 lessons
\n" ); document.write( "\"1.5a+%2B+7a+=+153\"
\n" ); document.write( "\"8.5a+=+153\"
\n" ); document.write( "\"a+=+18\"
\n" ); document.write( "The 1st lesson cost
\n" ); document.write( "\"1.5a+=+1.5%2A18\"
\n" ); document.write( "\"1.5a+=+27\"
\n" ); document.write( "The 1st lesson cost $27
\n" ); document.write( "check:
\n" ); document.write( "\"1.5a+%2B+7a+=+153\"
\n" ); document.write( "\"1.5%2A18+%2B+7%2A18+=+153\"
\n" ); document.write( "\"27+%2B+126+=+153\"
\n" ); document.write( "\"153+=+153\"
\n" ); document.write( "OK\r
