From midnight to 
8:00am, the temperature dropped 
0.55^(@)C each hour. If the temperature at 
8:00 am was 
4.6^(@)C, what was the temperature at midnight?
Answer: 
^(@)C

From midnight to 8:00am 8: 00 \mathrm{am} , the temperature dropped 0.55C 0.55^{\circ} \mathrm{C} each hour. If the temperature at 8:00 8: 00 am was 4.6C 4.6^{\circ} \mathrm{C} , what was the temperature at midnight?\newlineAnswer: \square C { }^{\circ} \mathrm{C}

Q. From midnight to 8:00am 8: 00 \mathrm{am} , the temperature dropped 0.55C 0.55^{\circ} \mathrm{C} each hour. If the temperature at 8:00 8: 00 am was 4.6C 4.6^{\circ} \mathrm{C} , what was the temperature at midnight?\newlineAnswer: \square C { }^{\circ} \mathrm{C}
  1. Calculate total temperature drop: Determine the total temperature drop from midnight to 88:0000 am. Since the temperature drops 0.55C0.55\,^\circ\mathrm{C} each hour and there are 88 hours from midnight to 88:0000 am, we multiply the hourly temperature drop by the number of hours. Calculation: 0.55C/hour×8hours=4.4C0.55\,^\circ\mathrm{C}/\text{hour} \times 8\,\text{hours} = 4.4\,^\circ\mathrm{C} total drop.
  2. Find temperature at midnight: Calculate the temperature at midnight.\newlineTo find the temperature at midnight, we add the total temperature drop to the temperature at 88:0000 am.\newlineCalculation: 4.6C+4.4C=9.0C4.6\,^\circ\mathrm{C} + 4.4\,^\circ\mathrm{C} = 9.0\,^\circ\mathrm{C}.
