Answer:
The constant of proportionality is 2.5. This can be expressed as (cups of sugar) * 2.5 = cups of flour
Explanation:
The constant of proportionality is y/x. Since flour comes second, we'll plug flour in for y here.
5/2 = 2.5
15/6 = 2.5
20/8 = 2.5
The constant of proportionality is 2.5. This can be expressed as (cups of sugar) * 2.5 = cups of flour
