Question 6

Solve the problem.
-The population of an endangered species of fish were moved to a controlled habitat to encourage the species to
increase in numbers. When they were moved there were 52 members in the population. In 18 months there
were 214 members in the population, with a growth pattern that was approximately linear. Draw a graph that
fits this data. On the graph, darken the part of the graph where the population is less than or equal to 100
members. Estimate, to the nearest month, how many months passed before the population reached 100.
