What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the percentage increase in the population be = A
Now , the equation will be
The initial population of the city = 117,000
The increase in population of the city = 136,890
Now , the percentage increase in population is given by the formula
initial population of the city + ( A / 100 ) x initial population of the city = increase in population of the city
So , on substituting the values in the equation , we get
Percentage increase in population = 117000 + ( A/100 ) x 117000 = 136890
117000 + ( A/100 ) x 117000 = 136890
Subtracting 117000 on both sides of the equation , we get
( A/100 ) x 117000 = 19890
Divide by 117000 on both sides of the equation , we get
A / 100 = 0.17
Multiply by 100 on both sides of the equation , we get
A = 17 %
Therefore , the value of A is 17 %
Hence , The percentage of increase in the population is 17 %
