Problema Solution
the population of a midwestern industrial town decreased from 219,000 to 215,000 in just 3 years. Assuming that this trend continues, what will the population be after an additional 4 years?
Answer provided by our tutors
The decrease rate is:
v = (219,000 - 215,000)/3
v = 4,000/3 people per year
t = 4 years
After t years the population will decrease by:
vt = (4,000/3)*4
After 4 years the population will be:
215,000 - (4,000/3)*4 = 209,667
