What is the constant rate of change if you started with an account value of $1,000 and after 3 years the account value was $1,750?

To find the constant rate of change, we need to calculate the change in account value per year.

The change in account value is the final value minus the initial value, which is $1,750 - $1,000 = $<<1750-1000=750>>750.
Since the time period is 3 years, we divide the change in account value by the number of years, $750/3 = $<<750/3=250>>250.
Therefore, the constant rate of change is $250 per year.
