Answer: Growth factor is 1.03 per year.
Correct option is C option.
Step-by-step explanation:
Given that water usage is increasing by 3% per year.
Time is measured in the years as given.
We need to find the growth factor for 3% increase per year.
We know a percent can be written decimal form by dividing by 100.
Therefore, 3% could be written as 3/100 = 0.03.
But the water usage would be increase by the factor of 1+0.03 that is 1.03.
Therefore, growth factor of increase in water usage would be 1.03.
