Answer:
Sure, here is the inequality that represents the number of gigabytes of data (G) you can use to stay under your budget of $130:
```
cost_per_gb * G <= budget
```
where:
* cost_per_gb is the cost of data per gigabyte, which is $10 in this case
* G is the number of gigabytes of data
* budget is your budget, which is $130 in this case
To solve this inequality, we can first subtract cost_per_gb from both sides of the inequality. This gives us:
```
G <= budget / cost_per_gb
```
We can then plug in the values for cost_per_gb and budget to get:
```
G <= 130 / 10
```
```
G <= 13
```
This means that you can use up to 13 gigabytes of data and still stay under your budget. If you use more than 13 gigabytes of data, you will exceed your budget.
Here is a table that shows the cost of data for different amounts of data:
```
| Amount of data (G) | Cost (\$) |
|---|---|
| 1 | 10 |
| 2 | 20 |
| 3 | 30 |
| ... | ... |
| 13 | 130 |
| 14 | 140 |
| ... | ... |
```
