Practice grid problem:
A population of 20 bobcats was introduced to a barrier island to help control the large rodent population. The bobcat population’s birth rate is .48 bobcats/year per capita and the death rate is .21 bobcats/year per capita. Given the initial bobcat population, predict the population size after 2 years on the island. Round to the nearest whole number.
