To find the constant rate of change, we can use the formula for the rate of change, which is:
\[ \text{Rate of Change} = \frac{\text{Final Value} - \text{Initial Value}}{\text{Time Period}} \]
In this case:
- Initial Value = $1,000
- Final Value = $1,750
- Time Period = 3 years
Plugging in the values:
\[ \text{Rate of Change} = \frac{1750 - 1000}{3} = \frac{750}{3} = 250 \]
Therefore, the constant rate of change is $250 per year.
