Answer :
Answer:
$1079.06
Explanation:
The formula for finding the amount of money at the end of 7 years is
[tex]y=a(1+r)^t[/tex]where
y = final amount
a = principle amount (the amount of money you started with)
r = interest rate as a decimal
t = number of years.
Now, in our case the above variables take the following values.
a = $820
r = 4% /100 = 0.04
t = 7 years
and putting these values into the above formula gives
[tex]y=820(1+0.04)^7[/tex][tex]y=1079.06[/tex]Hence, the amount of money in the account after 7 years will be $1079.06.
