    62 million gallons

    Step-by-step explanation:

    To get the amount of water to be used, we approximate it using an exponential equation.

    Mathematically;

    A = I (1 + r) ^t

    where A is the volume of water by the year 2025

    I is the volume of water in the year 2019 which is 55 million

    r is the rate of increase in water demand which is 2.1% or simply 2.1/100 = 0.021

    t is the number of years which is 2025-2019 = 6 years

    Now plugging these values into the exponential equation, we have;

    A = 55,000,000 (1 + 0.021) ^6

    A = 55,000,000 (1.021) ^6

    A = 62,304,173.899295434 gallons

    To the nearest million, this is equal to 62,000,000 gallons
