You invest $5,000 into an account where interest compounds continuously at 3.5%. How long will it take your money to double? Rou

salantis [7]

Answer:

20 years

Step-by-step explanation:

<u>Continuous Compounding Formula</u>

$\large \text{$ \sf A=Pe^{rt} $}$

where:

A = Final amount
P = Principal amount
e = Euler's number (constant)
r = annual interest rate (in decimal form)
t = time (in years)

Given:

A = $10,000
P = $5,000
r = 3.5% = 0.035

Substitute the given values into the formula and solve for t:

$\sf \implies 10000=5000e^{0.035t}$

$\sf \implies \dfrac{10000}{5000}=e^{0.035t}$

$\sf \implies 2=e^{0.035t}$

$\sf \implies \ln 2=\ln e^{0.035t}$

$\sf \implies \ln 2=0.035t\ln e$

$\sf \implies \ln 2=0.035t(1)$

$\sf \implies \ln 2=0.035t$

$\sf \implies t=\dfrac{\ln 2}{0.035}$

$\implies \sf t=19.80420516...$

Therefore, it will take 20 years (to the nearest year) for the initial investment to double.

What is 85% of 36= ??????

aliya0001 [1]

To find 85% of 36 we have to transform 85% into fraction and then multiply it by 36.
85% is $\frac{85}{100}$
$\frac{85}{100}*36= \frac{85*36}{100}= \frac{3060}{100} = \frac{153}{5} =30.6$ - its the result
