Answer:
$24
Step-by-step explanation:
Ten percent of 20 is 2.
The problem never says if he deposited any more money, so the account will always be at 20 dollars without interest.
If Lonny has his bank account for 2 years, the interest will be doubled.
Now, the interest is 20 percent.
If 10 percent of 20 is 2, then 20 percent will be 4.
Add 4 to 20 and you get 24.
