Question

a basketball team won 60% of the first 70 games it played. there are 40 games still to be played in the season. How many of the remaining games must the team win in order to end the season with a 70% win record?

Answer 1

.60*70 + x*40 = .70*110
x = .875

so, they must win 7/8 * 40 = 35 of the remaining games. Good luck with that...
