The balance of an interest-bearing account can be modeled by an exponential equation. For example, consider an initial deposit of $10000 at an annual interest rate of 5%. The Interest earned each year is deposited into the account at the end of the year. A. Assuming that no withdrawals or deposits are made, write an equatlon that models the account balance after x years. Your answer B. What is the account balance at the end of the 7 years? Your answer
