Based on the information provided:

1. The median amount they spent each week is **50**.
2. The difference of the first and third quartiles of the data set (also known as the interquartile range, IQR) can be calculated as follows:

- First quartile (Q1) = 20
- Third quartile (Q3) = 70

The difference is:
\[
\text{IQR} = Q3 - Q1 = 70 - 20 = 50
\]

So, the difference of the first and third quartiles of the data set is **50**.

Final answers:
- The median amount they spent each week is **50**.
- The difference of the first and third quartiles of the data set is **50**.
