The correct statements are:
A) Point (20, 100) represents earning 20 compliments.
C) Point (5, 1) represents the unit rate.
Here's the explanation for each statement:
A) Point (20, 100) represents earning 20 compliments:
In the given scenario, the student earns 25 stars for 5 compliments. This means that for every 5 compliments received, the student earns 25 stars. To find the number of stars earned for 20 compliments, we can use the unit rate of 5 compliments = 25 stars. Since 20 compliments is 4 times 5 compliments, multiplying the unit rate by 4 gives us 4 * 25 = 100 stars. So, the point (20, 100) represents earning 20 compliments.
C) Point (5, 1) represents the unit rate:
As mentioned above, the unit rate in this scenario is 5 compliments = 25 stars. Simplifying this ratio gives us 1 compliment = 5 stars. Therefore, the point (5, 1) represents the unit rate.
The other statements are not correct because they do not represent the scenario correctly or do not align with the given information.
