Problem 396
The Free Throw Problem. A basketball player has made 135 free throws in 180 attempts. Of the next 50 free throws attempted, how many would she have to make to raise her percent of free throws made by 5%?
Solution
135 free throws in 180 attempts so percentage is = 135*
=75%
Now we need to made it 80% for 180+50 = 230 attempts
80% of 230 = 230*0.80 = 184
Already made 135 free throws now need 184-135 = 49 free throws out of next 50 attempts.
