Solve.A rare baseball card was sold in 1990 for $ 227,000. The card was then resold in 1998 for $ 451,000. 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) = 227e0.764t, where t is the number of years after 1990. B. V(t) = 227,000e0.086t, where t is the number of years after 1990. C. V(t) = 227,000e0.764t, where t is the number of years after 1990. D. V(t) = 227e0.086t, where t is the number of years after 1990.
