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?(1 point)

The constant rate of change is $
per year.

To find the constant rate of change, we need to determine how much the account value increased each year.

The initial account value is $1,000 and after 3 years, it increased to $1,750.

The amount it increased over 3 years is $1,750 - $1,000 = $<<1750-1000=750>>750.

The constant rate of change is the increase divided by the number of years: $750/3 years = $<<750/3=250>>250.

Therefore, the constant rate of change is $250 per year. Answer: \boxed{250}.
