The US population in millions is P(t) today, where time t is measured in years. For each statement, choose one of the expression A-H that represents it. Solution P(t) is in millions 1) The population after 100,000 people have emigrated ==> Population is decreased by 100,000 = 0.1 million people ==> P(t) - 0.1 (Option D) 2) Ten percent of the population we have today ==> (10/100) P(t) = 0.1 P(t) (Option G) 3) Todays population plus 10 million immigrants = P(t) + 10 (Option H) 4) The population 10 years before today = P(t - 10) [ Option A].
