b = (3/5)M
\n" ); document.write( "---
\n" ); document.write( "r = M - b
\n" ); document.write( "r = M - (3/5)M
\n" ); document.write( "r = (5/5)M - (3/5)M
\n" ); document.write( "r = (2/5)M
\n" ); document.write( "---
\n" ); document.write( "p = (1/4)r
\n" ); document.write( "p = (1/4)(2/5)M
\n" ); document.write( "p = (1/10)M
\n" ); document.write( "---
\n" ); document.write( "b = p + 350
\n" ); document.write( "---
\n" ); document.write( "b = p + 350
\n" ); document.write( "(3/5)M = (1/4)r + 350
\n" ); document.write( "(3/5)M = (1/10)M + 350
\n" ); document.write( "(6/10)M - (1/10)M = 350
\n" ); document.write( "(5/10)M = 350
\n" ); document.write( "(1/2)M = 350
\n" ); document.write( "M = 700
\n" ); document.write( "---
\n" ); document.write( "answer: he had 700
