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 made 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.
