Accepted Solution

A:

Answer:81 millionStep-by-step explanation:A = Pe^rt Let's break this equation down.A is the total you will have.P is the starting value.R is the rateT is the time.Let's find the rate first.74000000 = 70000000e^7rDivide each side by 70mil74000000/70000000 = e^7rThen take the ln() of each side.ln(74000000/70000000) = 7r0.0556 = 7rr = 0.0079Now we can find how many people will be there in 2010.A = 70,000,000e^(19 * 0.0079)A = 81336530.2373Now we round to the nearest million, leaving us with 81 million.
