She is coaching 100 more games and we need to determine how many she must win to have a winning percentage of 70 percent. We can let w = the number of remaining games she must win. $$\frac{260 + w}{400 + 100} = \frac{70}{100}$$ $$\frac{260 + w}{500} = \frac{7}{10}$$ $$10(260 + w) = 3500$$ $$260 + w = 350$$ $$w = 90$$ GMAT/MBA Expert GMAT Instructor Joined 25 Apr 2015 Posted: 2791 messages Followed by: 18 members Upvotes: 43 M7MBA wrote: A basketball coach has won 65 percent of the 400 games she has coached in her career.
