**Marth**, Sunday, February 21, 2010 at 1:10pmHer current percentage of successes is 135/180 = 75%.

She now makes 50 more free throws, for a total of 180+50 = 230. She wants to get 75% + 5% = 80%. How many of those 230 does she need to make?

Subtract 135 to find the number of free throws out of the extra 50.
