**Answer:**

c. **3,147,200** water-filled glasses

**Step-by-step explanation:**

The amount of water consumed by an American per day= 100 gallons

So, the amount of water consumed by an American per week = 7×100 = 700 gallons

In 100 gallons of water 1,600 drinking glasses can be filled.

In 700 gallons of water 7×1,600= 11,200 drinking glasses can be filled.

The amount of water consumed by 281 American per week = 700×281 = 196,700 gallons

As in 700 gallons of water 11,200 glasses can be filled.

So, in 1 gallons of water glasses can be filled.

So, in 196,700 gallons of water glasses can be filled.
