Let's break down the problem step by step:

1. **Morning temperature**: Joaquin recorded 62°F in the morning.
2. **Afternoon increase**: The temperature increased by \(6 \frac{1}{2}\) °F (which is 6.5°F) in the afternoon.
3. **Evening decrease**: The temperature then decreased by 8.7°F in the evening.

### To calculate the evening temperature:
- Start with the morning temperature: 62°F.
- Add the afternoon increase: \( 62 + 6.5 = 68.5 \) °F.
- Subtract the evening decrease: \( 68.5 - 8.7 = 59.8 \) °F.

Thus, the evening temperature is **59.8°F**.

1. What is the effect of consecutive increases and decreases on the overall temperature?
2. How would the result change if the afternoon increase were larger?
3. How could this temperature problem be represented using a simple equation?
4. What if the temperature had increased by a different fraction in the afternoon?
5. How does understanding positive and negative changes in temperatures apply to real-world weather data?

### Tip: 
When solving temperature changes, always track increases and decreases in separate steps to avoid confusion.

Joaquin recorded a temperature of 62°F this morning for science class. The temperature increased 6 1/2°F in the afternoon before decreasing 8.7°F in the evening. What was the evening temperature?
