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. Approximately how much was the transaction volume in the year 2000?

$316 billions was 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 =

And the transaction volume (in billions of dollars) of purchases made on debit cards in the United States can be approximated by the equation:

As, is the number of years since 2000.

Thus, the value of

Now, solving the equation by putting the value of :

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

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.
