The future amount of money in the account after 15 years would be approximately $5229.
To calculate the future amount of money in the account, we can use the formula for compound interest:

In this case, the initial investment is $1,500, the growth rate is 100% (since the money doubles), the time is 15 years, and the compounding period is 12 years.
Substituting these values into the formula, we get:

Evaluating this expression gives us a future amount of approximately $5229.
