Final answer:
The customer will earn $2565 in interest and the account balance after 30 years will be $7065.
Step-by-step explanation:
To calculate the interest earned in 30 years, we can use the simple interest formula: I = P * r * t, where I is the interest, P is the principal amount, r is the interest rate, and t is the time in years.
To find the interest earned, we substitute the given values into the formula: I = 4500 * 0.019 * 30 = $2565.
To find the account balance after 30 years, we add the interest earned to the principal amount: Account Balance = P + I = 4500 + 2565 = $7065.
