Question

One thing a person can do to reduce his or her water footprint is to use less water every day. If each American was to reduce his or her daily water use by 2 m3 (528 gallons), how would you calculate the new annual water footprint for a typical American? There may be more than one correct answer.

Answer 1

Annual water footprint for a typical American in m3 − 2×365 m3

Step-by-step explanation:

We need the annual water footprint for a typical American first. Then, if each American was to reduce his or her daily water use by 2 m3, this would mean they would reduce his or her annual water use by 365×2 m3, since there are 365 days in a year, and this is the quantity that one needs to substract from the given annual water footprint for a typical American, also measured in m3.
