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 3^{o} per hour for 8 hours will result in a trop of 8 x 3^{o} = 24^{o}.

Since the temperature started at 36^{o}C, the new temperature will be 36^{o} - 24^{o} = 12^{o}C.
