In 1980, the population of blue whales in the southern hemisphere was thought to number 5,000. The population N(t) has been decreasing according to the formula $N ( t ) = 5,000 e ^ { - 0.1485 t }$ where t is in years and t = 0 corresponds to 1980. Predict the population in the year 2010 if this trend continues.
A) $3,203$
B) $50$
C) $58$
D) $4,942$
E) $1,797$
