| − | Since she will use <math>\frac{1} {5}</math> of her money to buy <math>\frac{1} {3}</math> of the CD's, she will use <math>\frac{3} {5}</math> of her money to buy all the CD's. Thus, she will have <math>1-\frac{3} {5}=\frac{2} {5}</math> of her money left. Hence, the answer is <math>\boxed{C}</math>
