The swimming pool is open when the high temperature is higher than 20^\circ\text{C}20 ? C. Lainey tried to swim on Monday and Th

Damm [24]

Answer:

$30-3d\leq 20$

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 $30^oC$ on Monday. So the decrease in temperature from Monday to Thursday will be $30-3d$ .

We have been given that the swimming pool is open when the high temperature is higher than $20^oC$ .

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:

$30-3d\leq 20$

Therefore, the inequality $30-3d\leq 20$ can be used to determine the rate of temperature decrease in degrees Celsius per day, d, from Monday to Thursday.
