b = no. of boys
\n" ); document.write( "g = no. of girls
\n" ); document.write( ":
\n" ); document.write( "Write an equation for each statement
\n" ); document.write( ":
\n" ); document.write( " 72 more girls than boys are enrolled in a school.
\n" ); document.write( "g = b + 72
\n" ); document.write( ":
\n" ); document.write( "60% of students are girls.
\n" ); document.write( "g = .6(g+b)
\n" ); document.write( "g = .6g + .6b
\n" ); document.write( "g - .6g = .6b
\n" ); document.write( ".4g = .6b
\n" ); document.write( "Replace g with (b+72)
\n" ); document.write( ".4(b + 72) = .6b
\n" ); document.write( ".4b + 28.8 = .6b
\n" ); document.write( "28.8 = .6b - .4b
\n" ); document.write( "28.8 = .2b
\n" ); document.write( "b = 28.8/.2

\n" ); document.write( "Check this by finding the no. of girls, then finding the percent
\n" ); document.write( "g = 144 + 72
\n" ); document.write( "g = 216 girls
\n" ); document.write( "then total students, 144 + 216 = 360
