The temperature in Houston at 6:00 a.m. was 36 degrees C. If the temperature drops 3 degrees each hour, what is the temperature in degrees Celsius at 2:00 p.m.?
From 6:00 am to 2:00 pm is 8 hours.
Dropping 3o per hour for 8 hours will result in a trop of 8 x 3o = 24o.
Since the temperature started at 36oC, the new temperature will be 36o - 24o = 12oC.
