The average of x numbers is 15.
\n" ); document.write( "the total of the 15 original numbers = 15x
\n" ); document.write( ":
\n" ); document.write( " If two of the numbers are each increased by y, the new average will be increased by how much?
\n" ); document.write( "15x+2y = total of x numbers now
\n" ); document.write( "Therefore
\n" ); document.write( " $\"%2815x%2B2y%29%2Fx\"$ = the new average
\n" ); document.write( ":
\n" ); document.write( "Find the difference in the averages
\n" ); document.write( " $\"%2815x%2B2y%29%2Fx\"$ - 15 = $\"%2815x%2B2y-15x%29%2Fx\"$ = $\"2y%2Fx\"$ is the dif in average
\n" ); document.write( " \n" ); document.write( "

\n" );
