Based on the interest rate and continuous compounding, the investment would double in value after 18.5 years.
We have given that,
investment to double at a 3 3/4% interest rate,
<h3>When will the investment double in value?</h3>
The future value using continuous compounding is:
= Amount x e ^ (rate x time)
Interest is
= 3.75%
<h3>What is the formula of an exponential function?</h3>
2 = e ^ (0.0375 x time)
In2 = 0.0375 x time
t = In2 / 0.0375
t= 18.5 years

Answer:
b
Step-by-step explanation:
Surface of the earth =3959×3.14
=12,437.565
if 20%is suitable so we multiply it by the surface
12,437.565×0.2=2,487.513 per people
2,487.513/7,700,00,00
So I think it will be the closest to b
