A person invested $1,500 in an account growing at a rate allowing the money to

double every 12 years. How much money would be in the account after 15 years, to
the nearest dollar?

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:
A = P(1 + r/n)^((nt))

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:
A = 1500(1 + 1/2)^((15/12))

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