What is the interest rate of the account? What is the balance after 10 years?
Interest rate: %
Balance after 10 years: $

Answer 1

The interest rate is $2, the balance after 10 years will be $60.

Explanation:

Each year the balance of the account increases by $2, so that would be the interest rate. After 10 years, the account will have 40 + 2 * 10 which equals $60.
