Answer: lt will take 28.09 years for the account value to reach $37800
Step-by-step explanation:
Hi, to answer this question we have to apply the compounded interest formula:
A = P (1 + r) t
Where:
A = Future value of investment (principal + interest)
P = Principal Amount
r = Annual Nominal Interest Rate (decimal form)
Replacing with the values given
37800= 9600 (1+0.05)^t
Solving for t (years)
37800/9600 = 1.05^t
3.9375 = 1.05^t
log 3.9375 = log 1.05^t
log 3.9375 = t (log 1.05)
log 3.9375/log 1.05 = t
t = 28.09 years
10 percent is the same as saying 0.10 so we simply do this sum of all parts approach.
You should get an answer a bit over 15000 if you plug it into your calculator. Remember, you are taxing a certain amount of dollars at each percentage so don't get hung up on the structure of the taxes. This is why we are subtracting the smaller number from the bigger
-40 + r > -23
Add 40 to both sides.
r > 17
<h3><u>The value of r is greater than 17.</u></h3>
