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%?

(135/180) x 100 = 75%

x/(180 + 50) x 100 = (75 +5)

x = 184

184 - 135 = 49

so basketball player would have to make 49 out of 50 free throws.
