If joe wins 18 of 30 games against mike. How many games in a row would joe have to win to have a 75% winning record
\n" ); document.write( "------
\n" ); document.write( "Solve::
\n" ); document.write( "Let the number of wins he needs be \"x\"::
\n" ); document.write( "(18+x)/(30+x) = 3/4
\n" ); document.write( "-----
\n" ); document.write( "4(18+x) = 3(30+x)
\n" ); document.write( "72+4x = 90+3x
\n" ); document.write( "x = 18 (# he would have to win)
\n" ); document.write( "-----------------
\n" ); document.write( "Proof (18+18)/(30+18) = 36/48 = 3/4 = 0.75
