To solve this problem, let us analyze this step by step. The temperature for each day is as follows:
Water temperature on Sunday = 78 degrees F
Water temperature on Monday = changed by -3 degrees F
Water temperature on Tuesday = changed by 3 degrees F
We can see that the total change of water temperature from Sunday to Tuesday is:
-3 + 3 = 0
Therefore there is zero overall change. There the integer which represents the temperature change is “0”.
Since the overall change in water temperature is zero, hence the temperature on Sunday and on Tuesday is similar.
Water temperature on Tuesday = 78 degrees F
