Answer:
The correct answer is A
Step-by-step explanation:
Because it is an exponential function, we know it goes up by a factor of the base of the exponential for each year. Since 2 is the base of the exponential, we know it goes up by a factor of 2 (otherwise known as doubling).
X = D/(1 - h)
1 - h = D/x
h = 1 - D/x
D = 400, X = 4000
h = 1 - 400/4000
h = 1 - 0.1 = 0.9
