Question

The temperature reading on a thermometer is 25°F at noon. During the afternoon, the temperature changes. What is the new reading for each temperature change?

### Temperature Change Problems

#### A. Scenario
- A person goes from a sauna at 115°F to an outside temperature of 30°F. 
- **Question:** What is the change in temperature?
  
#### B. Temperature Change Calculation
- The temperature reading on a thermometer is 25°F at noon. During the afternoon, the temperature changes. Determine the new reading for each temperature change:

  1. **Temperature rises by 10°F**
     - Calculation: \(25°F + 10°F = 35°F\)
  
  2. **Temperature falls by 2°F**
     - Calculation: \(25°F - 2°F = 23°F\)
  
  3. **Temperature falls by 30°F**
     - Calculation: \(25°F - 30°F = -5°F\)

#### C. Temperature Change from a Negative Reading
- The temperature reading on a thermometer is -15°F. Determine the new reading for each temperature change:

  1. **Temperature increases by 3°F**
     - Calculation: \(-15°F + 3°F = -12°F\)
  
  2. **Temperature decreases by 10°F**
     - Calculation: \(-15°F - 10°F = -25°F\)
  
  3. **Temperature increases by 40°F**
     - Calculation: \(-15°F + 40°F = 25°F\)

### Explanation
These exercises focus on understanding how temperatures change with additions or subtractions, taking into account positive and negative starting points.

### Temperature Change Exercises

---

#### Scenario A:
A person transitions from a sauna set at 115°F and observes a temperature change in their environment. What is the nature of this temperature change?

#### Scenario B:
The temperature indicated on a thermometer undergoes a change. Determine the new temperature reading based on the following options:

1. Rises by 10°F
2. Falls by 2°F
3. Falls by 30°F

#### Scenario C:
The thermometer displays a change in temperature. Identify the shift in temperature:

1. Increases by 3°F
2. Decreases by 10°F
3. Increases by 40°F

---

These exercises help students understand how to interpret changes in temperature using numerical shifts.
