Suppose there are 365 days in a year, then:

The weight of disposable chopsticks consumed in one day is: 800,000× ×5.5g=4.4 (ton).

The annual consumption of disposable chopsticks is: 4.4 (ton) ×365= 1606 (ton).

A: The weight of chopsticks consumed in one year is 1606 tons.

PS: Disposable articles are very harmful to the environment. I suggest you use it as little as possible or not. No business, no killing!
