Over time, the value of the property at 397 West Lake Street increased by 275%. If the initial value of the property was P, whic

larisa86 [58]

Answer: Third option is correct.

Step-by-step explanation:

Since we have given that

Initial value of the property = P

Rate of growth = 275%

So, we need to find the property's current value:

We will use "compound interest ":

$Amount=P(1+\dfrac{r}{100})^t\\\\Amount=P(1+\dfrac{275}{100})^1\\\\A=P(1+2.75)\\\\A=3.75P$

Hence, Third option is correct.

What does the interest rate have to be, if a bank pays interest, compounded continuously and the amount doubles in 5 years?

allochka39001 [22]

Let the original amount be A. Double that would be 2A.

Then, 2A = Ae^(r*5), or 2 = e^(5r).

Taking the natural log of both sides: ln 2 = 5r. Then r = (ln 2)/5 = 0.14

The interest rate would have to be 13.86% per year, written here as r=0.14.
