Assume that in one country in 2005, 13 % of the population was 65 or older. By 2050, this percent is expected to be 21.55%. The percent of the population ages 25-34 in 2005 was 13.9%. That age group is expected to include 13.1395% of the population in 2050.a. Assuming these population changes are linear, use the data for the 65 or over age group to write a linear equation. Then do the same for the 25-34 age group. Let x = 0 represent 2005 and x = 45 represent 2050. Express percents in decimal form.For the population of 65 or older the equation is y =For the population of 25-34 years the equation is y =
