The swimming pool is open when the high temperature is higher than 20°C. Lainey tried to swim on Monday and Thursday (which was 3 days later). The pool was open on Monday, but it was closed on Thursday. The high temperature was 30°C on Monday, but decreased at a constant rate in the next 3 days. What is the solution set of the inequality? (also please show the inequality to determine the rate of temperature decrease in degrees Celsius per day, x, from Monday to Thursday.)

30° - 3d ≤ 20°

Step-by-step explanation:

Here the constant rate of decreasing the temperature = d degree,

Thus, the total decreasing in three days = 3d degree,

If the temperature on Monday = 30°

Then the temperature n Thursday =  30° - 3d

Since, The swimming pool is open when the high temperature is higher than 20°

⇒ 30° - 3d ≤ 20°

Which is the required inequality to determine the rate of temperature decrease in degrees Celsius per day, d, from Monday to Thursday.
