The swimming pool is open when the high temperature is higher than 2 0 ∘ c 20 ∘ c. lainey tried to swim on monday and thursday (which was 3 3 days later). the pool was open on monday, but it was closed on thursday. the high temperature was 3 0 ∘ c 30 ∘ c on monday, but decreased at a constant rate in the next 3 3 days. write an inequality to determine the rate of temperature decrease in degrees celsius per day, d d, from monday to thursday.

Step-by-step explanation:  

Let d represent the rate of temperature decrease in degrees Celsius per day from Monday to Thursday.  

As temperature decreased at a constant rate in the next 3 days, so the rate of temperature will decrease 3d degree Celsius in 3 days.

We are told that the pool was open on Monday. The high temperature was on Monday. So the decrease in temperature from Monday to Thursday will be .

We have been given that the swimming pool is open when the high temperature is higher than .

As the pool was closed on Thursday. This means that temperature on Thursday was less than or equal to 20 degree Celsius. We can represent this information in an inequality as:

Therefore, the inequality can be used to determine the rate of temperature decrease in degrees Celsius per day, d, from Monday to Thursday.
