Question

A watering can dispenses water at a rate of 0.15 gallon per minute. The original volume of water in the can was 5 gallons. Which set of ordered pairs shows the volume of water in the can in gallons (y) as a function of time in minutes (x) from the first minute after the can starts dispensing water?

Answer 1

Answer: The Correct answer is {(1, 4.85), (2, 4.70), (3, 4.55)}.

Explanation:

I just did it. I don't really know how to explain it.

Answer 2

the 1st value is the time, and the 2nd value is the volume remaining in the can. the can is full at time x = 0 so y = 6.0 1 minute later x = 1 so y = 6.0 - 0.25 and for every 1 unit increase in x, y decreases by 0.25
