Suppose you invest 1600 at annual interest rate of 7.9% compounded cont how much will u have after 10yrs
frez [133]

Answer:

B. $3525.43

Step-by-step explanation:  

We will use continuously compound interest formula to solve our problem.

A=P*e^{rT}      

A= Amount after T years.

P= Principal amount.

r= Interest rate (in decimal form).

e= The mathematical constant e.

T= Time in years.

First of all we will convert our interest rate in decimal form.

7.9\text{ Percent}=\frac{7.9}{100}=0.079

Now let us substitute our given values in above formula.

A=1600*e^{0.079*10}

A=1600*e^{0.79}

A=1600*2.2033964262559365

A=3525.4342820094984\approx 3525.43

Therefore, we will get an amount of $3525.43 after 10 years and option B is the correct choice.
