Answer:

Step by step explanation:
We have been given that to cook a steak to medium-rare, it needs to have an internal temperature of 135 degree Fahrenheit.
Let t be the temperature to cook a steak.
We are told that a lower internal temperature than 135 degree Fahrenheit will under-cook the steak so steak cooked at temperature less than 135 degree will be under-cooked. We will not include 135 degrees as steaks are under-cooked at temperature less than 135 degrees.
Now let us write our inequality representing temperatures at which a steak will be under-cooked.
Therefore, inequality representing temperatures for under-cooked steaks will be
.
