Answer:
To the nearest million, this is 62,000,000 gallons
Step-by-step explanation:
Here, we are to calculate the amount of water expected to be used by Lee County in the year 2025.
To calculate this amount, we set up an exponential function as follows;
A = I(1+r)^t
where A is the amount expected in the year 2025
I is the initial amount of water used which is 55 million
r is the percentage change per year which is 2.1% or simply 2.1/100 = 0.021
T is the difference in the years between 2025 and 2019 = 2025-2019 = 6 years
Plugging these values into the equation, we have
A = 55,000,000(1 + 0.021)^6
A = 55,000,000(1.021)^6
A = 62,304,173.899295434
To the nearest million, this is 62,000,000 gallons
