Question

Levi spends a winter day recording the temperature once every three hours for science class. At 9 am, the temperature was -14.1°F. Between 9am and noon, the temperature rose 17.8°F. Between noon and 3pm, the temperature went down 16.8°F. Between 3pm and 6pm, the temperature dropped 12.3°F. What was the temperature at 6pm?

Answer 1

-25.4°F

Explanation:

-14.1 + 17.8 = 3.7

3.7 - 16.8 = -13.1

13.1 - 12.3 = -25.4
