Final answer:
The Smiths determined the future value of their $25,000 which will be $31,000 in 5 years.
Step-by-step explanation:
To calculate the $31,000 amount, the Smiths determined the future value of the $25,000.
Future value (FV) is the value of an investment or cash flow at a specified date in the future, based on the assumption that the cash flow will compound with a certain interest rate. In this case, the Smiths estimated that their $25,000 will grow to $31,000 in 5 years if it is deposited in a savings account that compounds interest yearly.
