Problem
In a recent basketball game, Shenille attempted only three-point shots and two-point shots. She was successful on 
of her three-point shots and 
of her two-point shots. Shenille attempted 
shots. How many points did she score?
Solution 1
Let the number of attempted three-point shots be 
and the number of attempted two-point shots be 
. We know that 
, and we need to evaluate 
, as we know that the three-point shots are worth 
points and that she made 
% of them and that the two-point shots are worth 
and that she made % of them.
Simplifying, we see that this is equal to 
. Plugging in , we get 
Solution 2 (cheap)
The problem statement implies that it doesn't matter how many two-point shots or three-point shots are attempted. If we assume that Shenille only attempts three-pointers, then she makes 
shots, which are worth 
points. If we assume Shenille only attempts two-pointers, then she makes 
shots, which are worth 
points.
