We are learning about multiplying and dividing positive and negative numbers.
The population has decreased by 300 residents, over the pass 5 years the same number of residents left each year.
What was the change in population each year?
Please help!!!!
In five years 300 people left
that is
300 people
----------- = 60 people/year
5 years
To find the change in population each year, we need to divide the total change in population by the number of years. In this case, the total change in population is -300 (since it has decreased by 300 residents) and the number of years is 5.
To calculate the change in population each year, we can use the formula:
Change in population per year = Total change in population / Number of years
Substituting the values, we get:
Change in population per year = -300 / 5
Now, let's solve the equation:
Change in population per year = -60
Therefore, the change in population each year is -60 residents.
