A frequency distribution for monthly savings:

| Savings ($) | Frequency | |---|---| | 0–100 | 4 | | 100–200 | 9 | | 200–300 | 14 | | 300–400 | 7 |

Using $Median = L + \left(\frac{\frac{n}{2} - CF}{f}\right) w$ where $L$ is the lower class boundary, $CF$ is cumulative frequency before the median class, $f$ is the median class frequency, and $w$ is class width, find the median.
