Question

The temperature at 6:00 a.m. was ‐3.5°C. From 6:00 to 7:00, the temperature increased 2.5°C. From 7:00 to 8:00, it decreased by 0.25°C, and from 8:00 to 11:00, the temperature dropped 3.25°C. Which expression shows the temperature in °C at 11:00 a.m.?

Answer 1

Explanation:

6:00 am 3.5 oC

6:00-700 = 3.5+0.25 = 3.75

7:00-8:00 = 3.75 - 0.25 = 3.50

8:00-11:00 = 3.50 - 3.25 = 0.25

T(11:00am) = 3.5 + 0.25 - 0.25 - 3.25

T(11:00am) = 0.25
