1) Julian is moving from his hometown of Sedona, Arizona, to Juneau, Alaska. He knows he is going to face a big temperature change, and he is getting ready. The hottest it gets in Sedona is 112 degrees F. The hottest it gets in Juneau is 72 degrees F. Approximately what temperature change will Julian experience?

Step-by-step:

- Hottest temperature in Sedona = 112°F
- Hottest temperature in Juneau = 72°F
- To find the temperature change, subtract the two:

$$
112 - 72 = 40
$$

So, Julian will experience a decrease of 40 degrees Fahrenheit.

✔ Answer: Julian will experience a temperature change of –40°F (a drop of 40 degrees).

> *Note: Since he’s moving from warmer to cooler, the change is negative.*

2) Abraham is spending a day at the hotel pool. He enjoys jumping from the very cool pool (62 degrees) to the very hot Jacuzzi (113 degrees). What temperature change is Abraham experiencing as he moves from pool to Jacuzzi?

Step-by-step:

- Temperature of pool = 62°F
- Temperature of Jacuzzi = 113°F
- Change in temperature = Final – Initial

$$
113 - 62 = 51
$$

✔ Answer: Abraham experiences a temperature change of +51°F (an increase of 51 degrees).

3) Zack just got a grade of 93 on a report. However, because he turned it in late, his teacher is going to deduct 15 points. What will Zack’s final score on the report be?

Step-by-step:

4) On Monday, Taylor lost 20 dollars to Zack when playing a card game. He was angry that he had lost, so he kept playing. On Tuesday, Taylor lost another 5 dollars. On Wednesday, he neither lost nor won. On Thursday Taylor lost another 7 dollars. By then, Taylor had lost all of his savings. How much money did Taylor have before he started playing?

Step-by-step:

We need to add up all the money Taylor lost:

- Monday: –20
- Tuesday: –5
- Wednesday: 0
- Thursday: –7

Total loss:

$$
-20 + (-5) + 0 + (-7) = -32
$$

Since he lost all his savings, this means he started with $32.

✔ Answer: Taylor had $32 before he started playing.
