Final answer:
As you increase the length of time involved, future values increase.
Step-by-step explanation:
When you increase the length of time involved, the future values increase.
For example, if you invest $100 with an annual interest rate of 5%, after 5 years the future value will be $128.05. But if you increase the length of time to 10 years, the future value will be $161.05.
In general, the longer the time period, the higher the future values.
