For any direct variation, the equation is of the form y = kx, where k is the constant of proportionality.
Given the equation: f = 2.5w
The constant of proportionality is 2.5.
This means that the ration of the cups of flour to the cups of water used in the recipe is 2.5
Answer:
w = 3.5
Step-by-step explanation:
