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.)
