Answer:
$6370
Explanation:
The simple interest formula gives us the final amount A given the principal amount P:
where r is the interest rate and t is the time interval.
Now in our case we have
P = 2800
r = 4.25/100
t = 30 years
therefore, the above formula gives
which simplifies to give
Hence, the account balance after 30 years will be $6370.
