Question

Over 20 years, the population of a town

decreased by 275 people to a population of
850. Write and solve an equation to find the
original population.

Answer 1

1125 people

Explanation:

We don't know the exact quantity, but we know it has decreased by 275 and it's currently 850, so we will represent it like this:

x - 275 = 850

x = original amount of people

Now we just solve it like any equation

x = 850 + 275

x = 1125

Hope it was helpful ;)

Answer 2

p= 1125

Explanation:

p-275= 850

p- 275= 850

+ 275 +275

p= 1125

P= the original population minus D= decrease in population is equal to C= the current population

p-d=c
