$2,000

Answer 1

1. Ans: 5 percent

Explanation:

P(1 + i)ⁿ = F

9,500(1 + i)¹⁰ = 15,000

(1 + i)¹⁰ = 15,000 / 9,500 = 1.5789

1 + i =

1 + i = 1.05

i = 1.05 - 1 = 0.05 or 5%.

2. Ans: $24,000

Explanation:

P(1 + i)ⁿ = F

9,500(1 + i)¹⁰ = 15,000

(1 + i)¹⁰ = 15,000 / 9,500 = 1.5789

1 + i =

1 + i = 1.0467

i = 1.0467 - 1 = 0.0467 or 4.67%

The world GDP per capita in 2030 = P(1 + i)^n

                                                       = 9,500(1 + 0.0467)^20

                                                       = $23,668

It is closest to $24,000.

3. Ans: $7,000

Explanation:

National income = C + I = 5,000 + 2,000 = $7,000
