1. **State the problem:** Myka starts hiking at a temperature of 68°F. The temperature drops by 5.4°F for every 1,000 feet she hikes up. We need to find the temperature after she hikes up 6,000 feet. 2. **Formula used:** The temperature change can be calculated using the formula: $$\text{Temperature after hike} = \text{Initial temperature} - (\text{Rate of temperature drop} \times \text{Elevation change in thousands of feet})$$ 3. **Calculate the elevation change in thousands of feet:** $$\frac{6,000}{1,000} = 6$$ 4. **Calculate the total temperature drop:** $$5.4 \times 6 = 32.4$$ 5. **Calculate the final temperature:** $$68 - 32.4 = 35.6$$ 6. **Answer:** The temperature after Myka hikes up 6,000 feet is **35.6°F**.
