A
4 °F
B
8 °F
C
12 °F
D
16 °
Answer:
D. 16 °F
Step-by-step explanation:
Given:
The initial temperature of the outside is 0 °F.
Decrease in the temperature in the first hour = 12 °F
Therefore, temperature after 1 hour = 0 - 12 = -12 °F
Now, decrease in the temperature in the second hour = 4 °F
Therefore, temperature after 2 hours = -12 - 4 = -16 °F
Let 'x' °F be added to the final temperature in order to bring it to 0 °F.
Therefore,
Adding 16 on both sides, we get:
Hence, we need to increase the temperature by 16 °F to attain the same initial temperature of 0 °F.
