Sample Problem

Your family needs 2 gallons of water this week, but you don’t want to buy any more than 8 gallons. Write an inequality representing the possible gallons of water you could buy this week.

Solution

Since your family needs 2 gallons of water, you must buy at least 2 gallons of water. If you don’t want to buy more than 8 gallons, it means you are willing to buy anywhere between 2 and 8 gallons of water, inclusive. The inequality for this is           2 ≤ g ≤ 8.
