m6|l12 solving problems about percent increase or decrease
the population of deer in a town increased by 25% from year 1 to year 2. the population of deer in year 2 is 15.
now write an equation that shows that the population in year 2 is a 25% increase of the population in year 1.
year 1: $x$
year 2: 15
125 % of year 1 population = year 2 population
$\square \cdot \square = \square$

Explanation:

Step1: Define Year 1 population

Let $x$ = Year 1 deer population.

Step2: Convert 125% to decimal

$125\% = \frac{125}{100} = 1.25$

Step3: Set up the equation

125% of Year 1 population equals Year 2 population.
$1.25 \cdot x = 15$

Answer:

$1.25 \cdot x = 15$
