Answer:

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

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 =
x.

And 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=133.4x+316

As,
x is the number of years since 2000.

Thus, the value of
x=0.

Now, solving the equation by putting the value of
x:


V=133.4* x+316\\\\V=133.4* 0+316\\\\V=0+316\\\\V=316.

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