Answer:$316 billionswas the transaction volume in the year 2000.Step-by-step explanation:Given:

The transaction volume V (in billions of dollars) of purchases made on debit cards in the United States can be approximated by the equation V = 133.4 x +316 , where x is the number of years since 2000.

Now, to find the transaction volume in the year 2000.

The number of years since 2000= [tex]x.[/tex]And the transaction volume [tex]V[/tex] (in billions of dollars) of purchases made on debit cards in the United States can be approximated by the equation:

[tex]V=133.4x+316[/tex]

As,[tex]x[/tex]is the number of years since 2000.[tex]x=0.[/tex]Thus, the value ofNow, solving the equation by putting the value of[tex]x[/tex]:[tex]V=133.4\times x+316\\\\V=133.4\times 0+316\\\\V=0+316\\\\V=316.[/tex]

Therefore,

$316 billions was the transaction volume in the year 2000.
