Problem:
Year........Population
1980..........67.38
1981..........69.13
1982..........70.93
1983..........72.77
1984..........74.66
1985..........76.60
1986..........78.59
Consider the formula P=67.38*(1.026)t
P=Population of Mexico in year t where t is the number of years from 1980. Confirm that this forumula gives the same population values as those given in the table.
Q1. Explain where the number 67.38 and the number 1.026 were obtained.
Q2. What would the population in 1990 have been if growth had continued in this same pattern?
