Hi.
\n" ); document.write( "there are 2 classes with an average of 62. One class of 36 students has an avg of 50 and the other class has an avg of 80. How many students are in the other class?\r
\n" ); document.write( "\n" ); document.write( "I know the answer is 24 but I am not sure why.

Let number of students in the other class, be N
\n" );
document.write( "Then total scores for this class is: 80N
\n" );
document.write( "Total scores for 36-student class: 36(50), or 1,800
\n" );
document.write( "Total number of students in both classes = N + 36
\n" );
document.write( "We then get the following SCORES equation: 80N + 1,800 = 62(N + 36)
\n" );
document.write( "80N + 1,800 = 62N + 2,232
\n" );
document.write( "80N – 62N = 2,232 – 1,800
\n" );
document.write( "18N = 432
\n" );
document.write( "N, or number of students in other class = , or  \n" );
document.write( "

\n" );
