The correct equation representing the number of pails of water over time, given the initial condition of starting with 4 pails and gaining 2 pails per trip, is y = 2x + 4. However, among the provided options, the only equation that aligns with the initial condition is y = x/2 + 4, which assumes that each trip takes 4 units of time and x represents elapsed time rather than the number of trips. This indicates a potential error in the homework question itself, as the other options do not accurately reflect the problem's parameters.

Start with 4 pails of water. Each trip, you gain 2 pails of water. What equation represents number of pails over time
Homework Equations
N/A
The Attempt at a Solution
y = 2x + 4 should be the correct answer.
But my options are
y=4x + 2
y=x/4 + 2
y=x/2 + 4
y=3x + 3
Why is it not 2x + 4?
