James purchased a certain baseball card on January 1. The function f(x) = 85(1.03)^x, where 0 ≤ x ≤ 10, gives the predicted value, in dollars, of the baseball card x years after James purchased it. What is the best interpretation of the statement "f(8) is approximately equal to 108" in this context?

AWhen the baseball card's predicted value is approximately 108 dollars, it is 8% greater than the predicted value, in dollars, on January 1 of the previous year.BWhen the baseball card's predicted value is approximately 108 dollars, it is 8 times the predicted value, in dollars, on January 1 of the previous year.CFrom the day James purchased the baseball card to 8 years after James purchased the card, its predicted value increased by a total of approximately 108 dollars.D8 years after James purchased the baseball card, its predicted value is approximately 108 dollars.
