Let's make an equation to show how to get how many people were in 105,000.
But, with a decrease, you have to decrease it from 100.
100-12.5
87.5
So it will be 87.5 of what it was previously. Now let's get to the equation.
.875x=105,000
Let's divide each side.
105,000÷.875
120,000
Let's check if this was a 12.5% decrease.
120,000×0.125
15,000
120,000-15,000
105,000
So the population of 2010 was 120,000 people.

Step-by-step explanation:
Example 1 Determine if the value 3 is a solution of the equation
4x - 2 = 3x + 1
Solution We substitute the value 3 for x in the equation and see if the left-hand member equals the right-hand member.
4(3) - 2 = 3(3) + 1
12 - 2 = 9 + 1
10 = 10
Ans. 3 is a solution.
