She earned $3 more per hour for office work than for gardening.
She earned $4 more per hour for office work than for gardening.
She earned $3 more per hour for gardening than for office work.

Answer 1

To compare Gigi's earnings per hour for gardening and office work, we need to calculate her hourly rate for each type of work.

**Gardening:**
- Total earnings = $65
- Total hours = 5

Earnings per hour for gardening:
\[
\text{Earnings per hour for gardening} = \frac{65}{5} = 13
\]

**Office Work:**
- Total earnings = $90
- Total hours = 9

Earnings per hour for office work:
\[
\text{Earnings per hour for office work} = \frac{90}{9} = 10
\]

Now, we compare the two hourly rates:
- Earnings per hour for gardening = $13
- Earnings per hour for office work = $10

Next, we find the difference:
\[
13 - 10 = 3
\]

Gigi earned $3 more per hour for gardening than for office work.

Therefore, the correct statement is:
**She earned $3 more per hour for gardening than for office work.**
