Answer:
a. 252,172,055
b. 278,418,326
Step-by-step explanation:
Population grows at an exponential rate. You can model the growth using the equation [tex]A=P(1+r)^t[/tex].
- A is the total amount
- P is the starting population
- r is the percentage rate as a decimal
- t is the number of years after 2000
a. In this situation, P = 281,400,000, r= 0.02, and t = 5.
[tex]A=P(1+r)^t\\A=228,400,000(1+0.02)^5\\A=228,400,000(1.02)^5\\A=252,172,055[/tex]
b. In this situation, P = 281,400,000, r= 0.02, and t = 10.
[tex]A=P(1+r)^t\\A=228,400,000(1+0.02)^10\\A=228,400,000(1.02)^10\\A=278,418,326 [/tex]
