Answer 1

To determine who makes more per hour, we can calculate the hourly wage for both Giovanna and Janet based on the information provided.

### Giovanna's Hourly Wage:
1. Calculate the total amount of money she made:
\[
42 + 28 + 35 + 21 + 49 = 175
\]
2. Calculate the total number of hours she worked:
\[
6 + 4 + 5 + 3 + 7 = 25
\]
3. Calculate her hourly wage:
\[
\text{Hourly wage} = \frac{\text{Total Money Made}}{\text{Total Hours Worked}} = \frac{175}{25} = 7
\]

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

### Comparison:
Giovanna makes $7 per hour, while Janet makes $9 per hour.

Based on our calculations:
- Giovanni makes **$7 per hour**.
- Janet makes **$9 per hour**.
