Answer:
35°F
Step-by-step explanation:
Given the following temperature values
On Wednesday morning = -12°F
Wednesday Afternoon = 23°F
Change in temperature will be the difference between the two temperatures as shown;
Change in temperature = 23°F - (-12°F)
Change in temperature = 23°F+12°F
Change in temperature = 35°F
Hence the change in temperature between morning and afternoon is 35°F
