Problema Solution
The problem of a certain city is 35% greater than it was 10 years ago. If the population in this city today is 105,000, What was the population 10 years age?
Answer provided by our tutors
We assume "The problem of a certain city" should read "The population of a certain city"
let 'x' represent the population 10 years ago, then
105000 = x + 0.35x
x=77777.777
The population 10 years ago would have been approximately 77,778
