Solve the problem.A rare baseball card was sold in 1990 for $215,000. The card was then resold in 1998 for $491,000. Assume that the card's value increases exponentially, and find an exponential function V(t) that fits the data. (Round decimals to three places.)
A. V(t) = 215,000e0.775t, where t is the number of years after 1990. B. V(t) = 215e0.775t, where t is the number of years after 1990. C. V(t) = 215,000e0.103t, where t is the number of years after 1990. D. V(t) = 215e0.103t, where t is the number of years after 1990.
