Answer 1

This years consumers purchased 5,234,267,990 bottles of water, let's called it X.

Last year consumers purchased 1,000,900,999 bottles of water, let's called it Y.

You need to find the best estimate of the number of bottles sold this year and last year, then you need to add both x and y:

`\begin{gathered} X+Y=5,234,267,990+1,000,900,999 \\ X+Y=6,235,168,989 \end{gathered}`

Thus, the answer is option C. 6,235,168,989
