Answer: 14 years
Step-by-step explanation:
The question states that an individual has $25,832.81 in a brokerage account, and plan to deposit an additional $4,000 at the end of every future year until the money in the account totals $210,000 and it's expected to earn 10% annually on the account.
To know the number of years that it'll take to reach the goal, we'll solve this in Excel as:
= =NPER (10%,-4000,-25832.81, 210000).
= 14 years
Therefore, it'll take 14 years to reach the goal.
