Answer:
Therefore after 16.26 unit of time, both accounts have same balance.
The both account have $8,834.43.
Explanation:
Formula for continuous compounding :
P(t)= value after t time
= Initial principal
r= rate of interest annually
t=length of time.
Given that, someone invested $5,000 at an interest 3.5% and another one invested $5,250 at an interest 3.2% .
Let after t year the both accounts have same balance.
For the first case,
P= $5,000, r=3.5%=0.035
For the second case,
P= $5,250, r=3.5%=0.032
According to the problem,
Taking ln both sides
Therefore after 16.26 unit of time, both accounts have same balance.
The account balance on that time is
=$8,834.43
The both account have $8,834.43.
