You can put this solution on YOUR website!
Let n be the number of books collected by the second team. Then the first team would be n-10; and the third team would be .3(n+n-10). So:
\n" ); document.write( "n+n-10+.3(2n-10)=65
\n" ); document.write( "2.6n=78
\n" ); document.write( "n=30
\n" ); document.write( "n-10=20
\n" ); document.write( ".3(2n-10)=15
\n" ); document.write( "The first team collected 20 books; the second team collected 30; and the third team collected 15. ☺☺☺☺ \n" ); document.write( "
