Please solve your other problem first before you try tackling this one. You need to know what to do with negative temperatures.

At noon the temperature was -3° C. Over the next four hours the temperature dropped another 15 degrees. Then every hour until 7:00 the temperature rose 2 degrees. What was the temperature at 7:00?
