Answer:
Account 1 would take 1 year or 12 months to double. Account 2 would take 10 years for its ammount to double.
Explanation:
Since Account 1 doubles each year, it would only take one year to reach the double. For Account 2, since it only increases by $100 each year, it would take 10 years to double. If 1,000 is divided by 100 we would be left with 10. By increasing the ammount by 100 for 10 years, we would be left with 1,000 after this alotted time.
