Problema Solution
A basketball team won 15 of the last 20 games. How many more games must they play, assuming they win half of those, to have an average of 60%?
Answer provided by our tutors
Let
x = the number of games left to play
x/2 = the number of games that they win out of x more games
(15 + (x/2))/(20 + x) = 0.6
by solving we find
x = 30 games
They need to play 30 more games.
