You put $1200 in an account that earns 3% simple interest. find the total amount in the account after four years.

First, before we do anything, let's find how much interest the account has earned over the four years.
Multiply 0.003 by 4 to get 0.12
This means the account earned 12% of interest over the four years.
Now, we need to find how much the account has earned.
Multiply 1200 by 0.12 to find how much interest it currently.
You get $144.
Now we add 144 to 1200.
We get $1344.
The total amount the account has earned after four years is $1344.
Hope this helped you! :)
