Answer:
$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 = [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.
Thus, the value of [tex]x=0.[/tex]
Now, 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.
