1. We are asked to find the average expected maximum temperature from Monday, June 24 to Sunday, June 30. 2. The maximum temperatures for these 7 days are: 29, 33, 28, 26, 22, 21, and 27 degrees Celsius. 3. The formula for the average (mean) temperature is: $$\text{Average} = \frac{\text{Sum of all temperatures}}{\text{Number of days}}$$ 4. Calculate the sum of the temperatures: $$29 + 33 + 28 + 26 + 22 + 21 + 27 = 186$$ 5. Calculate the average: $$\frac{186}{7}$$ 6. Show the division with cancellation: $$\frac{\cancel{186}}{\cancel{7}} = 26.5714...$$ 7. Round to 1 decimal place: $$26.6$$ 8. Therefore, the average expected maximum temperature from June 24 to June 30 is **26.6** degrees Celsius.
