If the water level at the lake continued to change at the same rate for 3 months in a row explain how you could estimate the total change in the water level at the end of the 3 months period.

  Multiply the 1-month change by 3 to get the 3-month change.

Step-by-step explanation:

You could add up the changes for the three months. Your problem statement tells you to assume they are the same:

  3-month change = (1-month change) + (1-month change) + (1-month change)

  3-month change = 3×(1-month change)

Multiplication was invented to simplify repeated addition.
