In Exercise,find the balance in the account after 10 years.
Vesnalui [34]

Answer: $ 3462.03

Step-by-step explanation:

The exponential equation for growth (compounded continuously) is given by :-

A=Pe^{rt}

, where P= Present value

r= growth rate  ( in decimal)

t= time

As per given , we have

P=$1900,  r = 6% =0.06  and t= 10

Substitute all the values in the above equation , we get

A=1900e^{0.06(10)}

A=1900e^{0.6}

A=1900(1.8221188)=3462.02572\approx3462.03  [To the nearest cent]

Hence, the balance in the account after 10 years = $ 3462.03

Makovka662 [10]
Hey!~

To get the answer all you would need to do is divide 589/31=19.
If you round $19 dollars up, the closest number would be $20. The answer is B. $20.00.

Hope this helps and have a great day!
