Problema Solution
The exponential equation P=208e^.008t describes the population of the United States in millions, t years after 1970
In what year will the population of the U.S. reach 325 million?
Answer provided by our tutors
P=208e^.008 = 325 , then
ln208+0.008t = ln325 , and
t=ln(325/208)/0.008=55.8
in year 1970+55.8=2025.8 population is doubled
