Questions 47 and 48 refer to the following laboratory investigation.
An APES class was doing field research using a mark-recapture technique to
estimate the population size of a particular species of butterfly. The size of
the field was exactly 2 hectares (ha) or 20,000 square meters. Initially, the
class caught and marked 150 of these butterflies in the field and then
released them. Later, the class recaptured 100 of this species of butterfly, of
which 20 were marked.

(A) 13
(B) 30
(C) 750
(D) 1,500
(E) 3,000
- What was the population density of the butterflies?
