An Ecologist Samples the Number of Individuals in a Population

An ecologist samples the number of individuals in a population of algae in water that is 10 m deep. He uses a 1 m² sampling technique, where he randomly drops a 1-m² square and then counts the number of individuals for this specific species of algae where it drops. He repeats this ten times and finds that the average number of individuals in the counts is 12. The total area covered by the population is 100 m². Using this method, how many individuals are in the population?

A) 12 × 10 × 100
B) 12 × 10
C) 12 × 100
D) 12 ÷ 10 × 100
E) 12 ÷ 100 × 10
