Chapter 5.2, Problem 66E
Solve each problem by using a system of three linear equations in three variables.
Age Groups In 1980 the population of Springfield was 1911. In 1990 the number of people under 20 years old increased by 10%, while the number of people in the 20 to 60 category decreased by 8%, and the number of people over 60 increased by one-third. If the 1990 population was 2136 and in 1990 the number of people over 60 was equal to the number of people 60 and under, then how many were in each age group in 1980?
