A biologist is conducting a long-term study of the decline of the frog population in a beaver pond. The population was 267 in 1995 and 178 in 2002. Assuming an exponential decay model, determine:

a) The annual decay rate as a percent;

b) The predicted population in 2010

c) The population in 1980.

d) How many frogs will the pond lose in the year 2005?
