The water level in a swimming pool decreases from 60in to 58.25in in one week. assuming that the water level changes at a constant rate, how much did the water level decrease each day?

-0.25 in, per day.

Step-by-step explanation:

Given : The water level in a swimming pool decreases from 60 in to 58.25 in in one week.

Here Initial water level = 60 in

Final water level = 58.25 in

And one week = 7 days

We assume that the water level changes at a constant rate.

Then the rate of change in water level will be given by :-

Hence, the water level decrease each day = -0.25 in, per day.
