Chapter 6 (Sevilla and Somers

Consider the formula

67 .38 (1 .026 )t . If we let

represent the population of Mexico in year t where t is the number of years from 1980 confirm that this formula gives the same population values given in the table in Example 6 .5

b . What would the population in 1990 have been if the growth had continued in the same pattern

Formula is given by

(1990 67 .38 (1 .026 )t , where

Population at 1990 , t number of years from 1980

to 1990

t (1980 0 This means that there is still no growth

t (1990 10 This means the rate of growth will be applied ten times

P (1990 67 .38 (1 .026 (10 67 .38 (1 .3523 87 .1778 87 .10
