At what rate should $1,000 be invested compounded continuously to produce a final balance of $2,000 in
5 years?
A. 0.139%
B. 0.231%
C. 13.863%
D. 23.105%

14.9%

Step-by-step explanation:

Using the compound interest formula;

A = P(1+r)^t

A is the amount = $2000

P is the principal = $1000

r is the rate

T is the time = 5 years

Substitute the given values into the formula;

2000 = 1000(1+r)^5

2000/1000 = (1+r)^5

2 = (1+r)^5

= 1 + r

r = 1.149 - 1

r = 0.149%

Hence the required rate is  14.9%

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
