In May, Ken spent $2,000 on transportation which was 1/4 of his salary. He gave his parents 1/8 of his salary. How much did he have left?
We start with $2,000. He then uses \(\frac14 + \frac18 = \frac38\) of his salary. This means he has \(1 - \frac38 = \frac58\) of his salary left. \($2000 \cdot \frac58 = $1,250\)
Thus, he has $1,250 left.
