The total interest accrued is $2,407.41 if you invested $7,000 into a money market account for 10 years at an annual interest rate of 3%. 
<h3>What is invested amount?</h3>
An investment is a payment made to acquire the securities of other firms with the intention of making a profit.
 
We are assuming the interest will be compounded annually

Where A = Final amount
           P = Principal amount
           r  = annual rate of interest
           n = how many times interest is compounded per year
           t = How long the money is deposited or borrowed (in years)
 
We have:
P = $7000
r = 3% = 0.03
t = 10 years
n = 1

After calculating:
A = $9407.41
I = A - P = 9407.41 - 7000 = $2,407.41
Thus, the total interest accrued is $2,407.41 if you invested $7,000 into a money market account for 10 years at an annual interest rate of 3%.
