12. The average of x numbers is 15.
\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( ":
\n" ); document.write( "We can write the original average as (for understanding purposes):
\n" ); document.write( " $\"%2815x%29%2Fx\"$ = 15 average
\n" ); document.write( ":
\n" ); document.write( "We add y to two of the numbers and we have
\n" ); document.write( " $\"%2815x%2B2y%29%2Fx\"$ = the new average
\n" ); document.write( ":
\n" ); document.write( "The difference between the two averages
\n" ); document.write( " $\"%2815x%2B2y%29%2Fx\"$ - 15
\n" ); document.write( "we can write it as two fractions
\n" ); document.write( " $\"%2815x%29%2Fx\"$ + $\"%282y%29%2Fx\"$ - 15
\n" ); document.write( "Cancel x, 15 is eliminated
\n" ); document.write( "15 + $\"%282y%29%2Fx\"$ - 15 = $\"2y%2Fx\"$ is the increase in average \n" ); document.write( "

\n" );
