Final answer:

To find the amount of money in the account after 14 years, we can use the formula for compound interest. Plugging in the values, the amount would be approximately $6,860 to the nearest ten dollars.

Step-by-step explanation:

To find the amount of money in the account after 14 years, we can use the formula for compound interest:

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

Where:

  • A is the amount of money in the account after the specified time period
  • P is the principal amount (initial investment)
  • r is the annual interest rate (written as a decimal)
  • n is the number of times the interest is compounded per year
  • t is the number of years

In this case, Carson invested $3,900 with an interest rate of 2.1% compounded monthly, so:

  • P = $3,900
  • r = 2.1% = 0.021
  • n = 12 (compounded monthly)
  • t = 14 years

Plugging these values into the formula:

A = $3,900(1 + 0.021/12)^(12*14)

Calculating this equation gives us approximately $6,856.86. Therefore, the amount of money in the account after 14 years would be $6,860 (to the nearest ten dollars).
