In her latest game, Ann bowled 199 and raised her average from 177 to 178. To raise her average to 179 with the next game, she must bowl:\r
\n" ); document.write( "\n" ); document.write( "a. 179 b. 180 c. 200 d. 201 e. None of these
\n" ); document.write( "--------------
\n" ); document.write( "Avg = sum of scores/# of games
\n" ); document.write( "A = S/n
\n" ); document.write( "177 = S/n --> S = 177n
\n" ); document.write( "178 = (S+199)/(n+1)
\n" ); document.write( "Sub for S
\n" ); document.write( "178 = (177n+199)/(n+1)
\n" ); document.write( "178*(n+1) = 177n+199
\n" ); document.write( "178n+178 = 177n+199
\n" ); document.write( "n = 21 (# of games averaged)
\n" ); document.write( "S = 22*178 = 3916 (after 22 games)
\n" ); document.write( "---------------
\n" ); document.write( "The next game will be #23
\n" ); document.write( "23*179 = 4117 (23 games times 179 avg)
\n" ); document.write( "4117-3916 = 201
\n" ); document.write( " \n" ); document.write( "
\n" );
