Greetings!
A)
If you can see, every 4 minutes the amount of water is increasing at a constant rate.
197 - 153 = 44
285 - 241 = 44
This means that at 8 minutes, because there is 153 gallons already in, we can divide 8 by 4 to see how many groups of 4 minutes there were.
8 ÷ 4 = 2
So then we can subtract two lots of 44 from 153:
153 - (44 x 2) = 65
So the starting amount was 65.
B)
The answer to B is the second option, because it is true that the amount of water is increasing. This is by 44 gallons per 4 minutes.
The amount of gallons per minute can be found out by dividing the amount by 4:
44 ÷ 4 = 11
So it is 11 gallons per minute.
Hope this helps!
