The constant of proportionality appears at the ratio (2, 5).
Explanation:
From the table, we can see the following ratios between the number of scoops of raspberry and the number of cups of lemonade:
- When there is 1 scoop of raspberry, there are 2.5 cups of lemonade. This can be written as 1:2.5.
- When there are 2 scoops of raspberry, there are 5 cups of lemonade. This can be written as 2:5.
- When there are 4 scoops of raspberry, there are 10 cups of lemonade. This can be written as 4:10.
- When there are 6 scoops of raspberry, there are 15 cups of lemonade. This can be written as 6:15.
We can see that the ratio of the number of scoops of raspberry to the number of cups of lemonade remains constant at 2:5.
Use the table to answer the question.
