Each type of fish thrives in a specific range of temperatures. The optimum temperatures for sharks range from 18 degrees Celsius to 22 degrees Celsius. Write an inequality that represents the temperatures where sharks will NOT thrive.
I believe the correct answer would be the water would be >18c or <22c, because it has to be less than 18 or greater than 22 since that temp. and the temp in between they would thrive.
