Answer:
The balance of Lea's account after 12 years of investment will be $ 21,694.04.
Explanation:
To calculate the compound interest generated by Lea's account, which has an annual interest of 8% compounded monthly, and whose investment will last for a period of 12 years, the following calculation must be performed:
X = 8,333 x (1 + 0.08 / 12) ^ 8x12
X = 21,694.04
Thus, the balance of Lea's account after 12 years of investment will be $ 21,694.04.
