Answer:
It will be 87.6 at 10pm
Explanation:
First, we had to find out how many hours passed between 4pm to 10pm. If we count, we will find that 6 hours passed. Next, multiply 2.4 by 6. This will give us how much the temperature dropped in 6 hours. We can do this because we know it dropped by 2.4 every hour. After you do 2.4*6, you will get the answer 14.4. This is how much the temperature dropped in 6 hours. Next, do 102-14.4. You will get 87.6. This means that the temperature at 10pm will be 87.6.
