To determine which statement correctly describes the relationship between the amount of money the student makes (Fee in dollars) and the time (Time in Days), we first need to analyze the values given:
- When the time is 0 days, the fee is $20. This suggests that there might be a starting fee or base fee of $20.
- The trend in the graph generally describes how the fee increases over time.
From the question, we need to establish the incremental charge per day. If we take the information provided, we see that over a span of time (let's say 10 days), if the fee is $20 at day 0, the increase in the fee will be the difference in the amount charged after 10 days divided by the number of days, which can be inferred from how the fee rises.
If we assume that the fee after 10 days (still not given explicitly) shows a linear relationship, we can piece together that:
If referring back to the choices:
- A suggests $11 plus an additional $20 per day: means $11 as a one-time charge and increases by $20 daily.
- B suggests $20 plus an additional $11 per day: starts at $20 and adds $11 daily.
- C suggests $20 plus an additional $10 per day: starts at $20 and adds $10 daily.
- D suggests $10 plus an additional $20 per day: starts at $10 but then vastly increases by $20.
If the information says the fee is $20 at day 0, and if one assumes that by day 10 the fee would be $100 (hypothetical for understanding), the increase would be $80 over 10 days. That means there is an increment of $8 per day generally.
However, since we're asked to choose, based on the analysis:
If we conclude that it appears the student charges a base fee of $20 (at day 0) and seems to add a lesser increment everyday, out of these options, C is the most fitting option as it conveys having $20 as a base fee.
So the answer is C. The student charges $20 plus an additional $10 per day.
