month, the total water used over a year, and how much additional water he would
need if he wanted to double the amount used each month after 12 months.
MCQs:
How much water will the farmer use in the 12th month?
What will be the total water usage over 12 months?
If the farmer decides to double his monthly usage after 12 months, how much water will he use in the 13th month?
By how much would the farmer's total annual water usage increase if he continued doubling the monthly amount after 12 months for the next 12 months?
