Question

a town's population grew from 7500 people to 8210 over a span of 10 years. By how many people did the population grow in those 10 years

Answer 1

Answer:
710 People
Step-by-step explanation:
If the population grew by X. Then we could say that the population grew from a starting population plus X to equal the new population 8210.
To clarify:
Old population: 7500
+
Population growth: X
=
New Population: 8210
Therefore,
8210=7500+X (Now get the variable by itself)
8210(-7500)=7500+X(-7500)
710=X
The Popoulation grew by 710 people
