To find this we will first find out how much interest they accrued within 20 years. We'll do that by multiplying all the given factors:
2000 x 0.049 x 20 = 1960
This shows they have made $1,960 in accrued interest. We'll add this sum by the original deposit they made of $2,000.
2000 + 1960 = 3960
In the end of 20 years of accrued interest, the person will have a total of $3,960 in their account.
