You can put this solution on YOUR website!
Assume she makes the next X shots, this would be the minimum number of shots she'd have to take.
Calculate the percentage of shots made,
%284%2BX%29%2F%2815%2BX%29%3E=60%2F100=3%2F5
5%284%2BX%29%3E=3%2815%2BX%29
20%2B5X%3E=45%2B3X
2X%3E=25
X%3E=25%2F2
Since the number of free throws is an integer, use the next largest integer.
X=13
