Question

Whaats question a & b ?

Answer 1

a. 252,172,055

b. 278,418,326

Explanation:

Population grows at an exponential rate. You can model the growth using the equation
`A=P(1+r)^t`.

• 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.

`A=P(1+r)^t\\A=228,400,000(1+0.02)^5\\A=228,400,000(1.02)^5\\A=252,172,055`

b. In this situation, P = 281,400,000, r= 0.02, and t = 10.

`A=P(1+r)^t\\A=228,400,000(1+0.02)^10\\A=228,400,000(1.02)^10\\A=278,418,326`
