Final answer:
The highest temperature of 5°C converts to 41°F using the temperature conversion formula, indicating that it is cold enough for wearing a bubble jacket.
Step-by-step explanation:
To convert the temperature from degrees Celsius to degrees Fahrenheit, you can use the following formula: (°C × 9/5) + 32 = °F. In this case, the highest temperature of the day is 5°C. Applying the formula, we get (5 × 9/5) + 32 = 41°F. Therefore, the predicted high temperature in degrees Fahrenheit for the day is 41°F, which is relatively cold and suitable for wearing a bubble jacket.
