The 3 that represent in this function is the "A. The amount of rainfall in week 0." zero weeks have passed, and there's already up to the 3 mark. if additional rain comes into the bin, the existing water is still thereso we add +3 every time
These are the following choices:
A. The amount of rainfall in week 0.
B. The week that Erin collected data.

Answer:

The amount of rainfall in week 0

Explanation:

because, 3 is the y-intercept, and w stands for the week it is.  

If w =0 , as in it is week 0 (before she collected data) then you substitue 0 into the equation for w you get 3.  That means even before she collected data there were already 3 inches of rain.  So, the answer should be 1.
