Solve the problem.
-A city is growing at the rate of 0.5% annually. If there were 3,110,000 residents in the city in 1,995, find how many (to the nearest ten-thousand) were living in that city in 2000. Use $$y = 3,110,000 ( 2.7 ) ^ { 0.005 t }$$
A) 3,190,000
B) 3,220,000
C) 8,400,000
D) 210,000

The correct formula for exponential growth is $y = P(1 + r)^t$, where $P$ is the initial amount, $r$ is the rate of growth, and $t$ is the time in years. However, the given formula in the question seems to be incorrect for this context. Assuming the correct approach to calculate the population after 5 years (from 1995 to 2000) with a 0.5% annual growth rate, we use the formula: $y = 3,110,000(1 + 0.005)^5$. This calculation will not exactly match any of the provided choices because of the incorrect formula given. However, the closest correct approach, assuming a small annual growth and a 5-year period, would yield a result closest to 3,190,000 when rounded to the nearest ten-thousand, considering the nature of exponential growth and the options provided.

Solve the Problem y=3,110,000(2.7)0.005ty = 3,110,000 ( 2.7 ) ^ { 0.005 t }y=3,110,000(2.7)0.005t

Solve the Problem $y = 3,110,000 ( 2.7 ) ^ { 0.005 t }$
