32. The temperature of a walk-in freezer is -2 degrees F, which increases by 3 degrees F each time a new item is added. What is the ending temperature if five items were added?
Answer: C
The ending temperature after adding five items is 13 degrees F.
When five items are added to the walk-in freezer, the temperature increases by 3 degrees F for each item added. Therefore, the total increase in temperature is 5 items multiplied by 3 degrees F, which equals 15 degrees F. Starting from an initial temperature of -2 degrees F, the final temperature is -2 + 15 = 13 degrees F.
A) 17 degrees F
This option is incorrect as it suggests that the final temperature would be 17 degrees F. The calculation shows that the increase of 15 degrees F from the initial temperature of -2 degrees F leads to a final temperature of 13 degrees F, not 17 degrees F.
B) -13 degrees F
This option is also incorrect. A temperature of -13 degrees F implies a decrease instead of an increase. The initial temperature of -2 degrees F increases by 15 degrees F when five items are added, resulting in a positive final temperature.
C) 13 degrees F
This option is correct. By calculating the increase of 15 degrees F from an initial temperature of -2 degrees F, the final temperature reaches 13 degrees F, confirming that this option accurately reflects the scenario described.
D) -17 degrees F
This option is incorrect as it indicates an even lower temperature than the initial one. The process of adding items causes the temperature to increase, not decrease, which is contrary to the result of -17 degrees F.
Conclusion
The correct answer, 13 degrees F, results from accurately applying the temperature increase formula based on the number of items added. All other options fail to consider the positive increase in temperature, leading to incorrect conclusions based on the initial temperature given.
