Question 936519: Please help me with this problem:
For a scientific experiment, a physicist must make sure that the temperature of a metal at 0 �C gets no colder than -80 �C. The physicist changes the metal�s temperature at a steady rate of -4 �C per hour.
a. Let t represent temperature in degrees Celsius. Write an inequality. Use the fact that the rate of change in temperature times the number of hours equals the final temperature.
I am confused on how to write the equation and where the t will fit in.

The rate of change is -4 degrees C per hour and
a) final temperature = t -4h, where t is the current temperature and h is the number of hours
