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?

Rationale

Adding five items to a walk-in freezer at -2 degrees F results in an ending temperature of 13 degrees F.

Starting from -2 degrees F and increasing by 3 degrees F for each of the five items, the calculation is -2 + (3 × 5) = -2 + 15 = 13 degrees F.

A (17 degrees F) YOUR ANSWER

This option suggests a total increase that would require a different starting point or a greater number of items added. The correct calculation shows an increase of 15 degrees F from -2 degrees F, leading to 13 degrees F, not 17 degrees F.

B (-13 degrees F) YOUR ANSWER

Choosing -13 degrees F implies a decrease in temperature rather than an increase. Adding five items results in a total of 15 degrees F added to the initial temperature of -2 degrees F, which does not support this option.

C (13 degrees F) CORRECT

This is the correct answer, as it accurately reflects the temperature change from -2 degrees F after adding five items. Each item raises the temperature by 3 degrees F, leading to a total increase of 15 degrees F, which results in an ending temperature of 13 degrees F.

D (-17 degrees F) YOUR ANSWER

This choice indicates a further decrease in temperature, which contradicts the problem's premise of adding items that raise the temperature. The calculation shows a positive temperature change that leads to a significantly warmer ending temperature.

Conclusion

The problem illustrates how incremental changes affect starting temperatures in a walk-in freezer. By calculating the temperature increase with each added item, it becomes evident that the final temperature after adding five items increases from -2 degrees F to 13 degrees F. Thus, understanding the arithmetic progression is crucial to determining the final condition accurately.

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?

Adding five items to a walk-in freezer at -2 degrees F results in an ending temperature of 13 degrees F.
