The problem asks us to find the average day temperature for the week, using the day temperatures provided in the table. The answer should be rounded to one decimal place.

1. Problem Description

The problem asks us to find the average day temperature for the week, using the day temperatures provided in the table. The answer should be rounded to one decimal place.

2. Solution Steps

First, we need to list the day temperatures for each day of the week from the table:

Monday: $33$

Tuesday: $29$

Wednesday: $32$

Thursday: $34$

Friday: $32$

Saturday: $30$

Sunday: $30$

Next, we need to calculate the sum of these temperatures.

$Sum = 33 + 29 + 32 + 34 + 32 + 30 + 30 = 220$

To find the average day temperature, we need to divide the sum of the temperatures by the number of days, which is $7$.

$Average = \frac{Sum}{Number \ of \ days} = \frac{220}{7}$

$Average = 31.42857...$

Finally, we need to round the average temperature to one decimal place.

$Average \approx 31.4$

3. Final Answer

The average day temperature for the week, correct to one decimal place, is $31.4$ °C.
