Guidance for solving Exercise 4 on page 46 of Math Grade 4 Workbook.

Problem Statement: A commune has 5256 people. After one year, the population increases by 79 people. After another year, the population increases by 71 people. Questions: a) After two years, how many more people did the population of the commune increase by? b) After two years, how many people are there in the commune?

Solution Method:

* Given Information:

- Population of a commune: 5256 people

- After one year: Population increases by 79 people

- After another year: Population increases by 71 people

* Problem Requirement:

- Calculate the increase in population of that commune after two years.

- Calculate the population of that commune after two years.

* Solution Method:

- To calculate the increase in population of that commune after two years, add the population increase in the first year to the population increase in the second year.

- To calculate the population of that commune after two years, add the initial population to the number of people increased after two years (just found).

Answer:
a) The increase in population of that commune after two years is:
79 + 71 = 150 (people)
b) Two years later, the population of that commune is:
5256 + 150 = 5406 (people)
b) 5406 people.
