Starting at noon, the temperature dropped steadily at a rate of 0.8 degrees Celsius every hour. For each of these situations, write and solve an equation and describe what your variable represents.
(1.) How many hours did it take for the temperature to decrease by 4.4 degrees Celsius?
(2.) If the temperature after the 4.4 degree drop was -2.5 degrees Celsius, what was the temperature at noon?
Match this situation with one of the equations.
