### Giovanna's Hourly Wage:
1. Calculate the total amount of money she made:
\[

\]
2. Calculate the total number of hours she worked:
\[
6 + 4 + 5 + 3 + 7 = 25
\]

\text{Hourly wage} = \frac{\text{Total Money Made}}{\text{Total Hours Worked}} = \frac{175}{25} = 7
\]

### Janet's Hourly Wage:

18 + 72 + 54 + 81 + 27 = 252
\]
2. Calculate the total number of hours she worked:
\[
2 + 8 + 6 + 9 + 3 = 28
\]
3. Calculate her hourly wage:
\[
\text{Hourly wage} = \frac{\text{Total Money Made}}{\text{Total Hours Worked}} = \frac{252}{28} = 9
\]
