Answer: Single deposit by Edward=$3594 to make it amount for college=$50,000 in 10 years.
Step-by-step explanation:
Here Compound amount =$50,000
Time=10 years
Rate of interest=4.3%
By the Daily compound interest formula ,we have
[tex]Amount=Principal(1+rate/365)^{365\times\ time}\\\Rightarrow\ Amount=Principal(1+4.3/365)^{365\times\ 10}\\\Rightarrow\ 50000=P(1+.011)^{3650}\\\Rightarrow\ 50000=P(1.011)^{3650}\\\Rightarrow\ 50000=P(13.911)...........(approx)\\\Rightarrow\ P=\frac{50000}{13.911}=3594......(approx)[/tex]
Therefore Principal amount deposited by Edward is $3594.
Answer:
$32,526.67
Step-by-step explanation:
Let the Principle be P
amount here A= $50,000
time n= 10 years n= 10*365=3650 days
rate of interest= 4.3% compounded daily= 4.3/365
let us use compound interest formula to calculate the principle
[tex]A= P(1+\frac{r}{100})^n[/tex]
putting all the values we get
[tex]50000=P(1+\frac{4.3}{100\times365})^10times365[/tex]
on solving we get P= $32,526.67
therefore he need to deposit $32,526.67
