$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 = $$x.$$ 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 $$x$$: $$V=133.4\times x+316\\\\V=133.4\times 0+316\\\\V=0+316\\\\V=316.$$ Therefore,$316 billions was the transaction volume in the year 2000.
