To find the rate at which Cole is saving, we need to use the formula for average rate of change:

Average rate of change = (change in quantity)/(change in time)

In this case, the "quantity" is the amount of money Cole saves, and the "time" is the number of months.

The change in quantity is:

$265 - $190 = $75

The change in time is:

3 months - 0 months = 3 months

Therefore, the average rate of change is:

Average rate of change = (change in quantity)/(change in time) = $75/3 months = $25/month

So, Cole is saving money at a constant rate of $25 per month.
