Looking at the picture attached, you will notice that on one side, we have a side of length 7+5=12. Next, we have a side length of 4+5+2=11. Hence, as length*width=area for a rectangle, this is the overall area of the rectangle. Next, in the picture, there are clearly two sides taken out - a 2x5 as well as a 4x5 rectangle, which are subtracted from the total area, resulting in 11*12-2*5-4*5

What is the total investment of $2150 invested at 5.3% for 16 years and compounded continuously?

sladkih [1.3K]

Answer:

The total investment is $5020.19

Step-by-step explanation:

Given : $2150 invested at 5.3% for 16 years and compounded continuously

To find : What is the total investment?

Solution :

The formula of continuously compounded interest is

$A = Pe^{rt}$

Where A = amount invested

P = principal = $2150

e = Euler's number (on calculator)

r = interest rate as decimal = 5.3%=0.053

t = time in years = 16 years

Substitute the value in the formula,

$A = Pe^{rt}$

$A = 2150\times e^{0.053\times 16}$

$A = 2150\times e^{0.848}$

$A = 2150\times 2.3349$

$A = 5020.19$

Therefore, Option 4 is correct.

The total investment is $5020.19.
