Answer

Explanation:

Step1: Represent initial temperature

The temperature before sunrise was 22.4°F below zero, so it is - 22.4°F.

Step2: Consider temperature - rise

It rose 12.8°F by noon. To find the temperature at noon, we add the rise to the initial temperature. The expression is - 22.4+12.8.

Answer:

B. -22.4 + 12.8
