Final answer:
Carlotta can download at most 3 more songs this week as she has a limit of 16 downloads and she has already downloaded 13. The inequality representing this situation is x ≤ 3. The graph includes all numbers to the left of and including point 3 on a number line.
Step-by-step explanation:
To figure out how many more songs Carlotta can download after already downloading 13 song files on the Hot-Burn music service, we write an inequality. Let x represent the number of songs Carlotta can still download this week. The inequality is:
x ≤ 16 - 13
This simplifies to:
x ≤ 3
Carlotta can download at most 3 more songs this week since she cannot exceed her limit of 16 total downloads.
Solving the inequality:
The solution set consists of all numbers less than or equal to 3. To graph this inequality on a number line:
- Draw a number line.
- Mark the point corresponding to 3.
- Shade the region to the left of this point (including the point) to represent all possible download amounts that are less than or equal to 3.
