Here are the solutions to your questions:

1. & 2. Draw and Display a combined bar and line graph:
To create a combined bar and line graph:

Step 1: Set up the axes. Draw a horizontal axis (x-axis) for the months (J, F, M, A, M, J, J, A, S, O, N, D). Draw a vertical axis (y-axis) for the amount, ranging from 0 to at least 700 to accommodate both spending and saving values. Label the y-axis "Amount".
Step 2: Plot spending as a bar graph. For each month, draw a bar whose height corresponds to the spending value for that month. For example, for January, draw a bar up to 350.
Step 3: Plot saving as a line graph. For each month, place a point at the height corresponding to the saving value for that month. For example, for January, place a point at 400. Once all points are plotted, connect them with a line.
Step 4: Add a legend and title. Include a legend to distinguish between the bars (spending) and the line (saving). Give the graph a clear title, such as "Monthly Spending and Saving".

3. What is the average yearly savings?

Sum all the monthly savings.
$\text{Total Savings} = 400 + 500 + 400 + 400 + 300 + 400 + 500 + 400 + 600 + 400 + 500 + 700 = 5900$
Divide the total savings by the number of months (12).
$\text{Average Savings} = \frac{5900}{12} = 491.67$
The average yearly savings is $\boxed{\text{491.67}}$

4. Name the month with the highest expenditure.
By examining the "spending" row, the highest value is 490. This occurs in November.
The month with the highest expenditure is $\boxed{\text{November}}$

5. Which month had the most saving?
By examining the "saving" row, the highest value is 700. This occurs in December.
The month with the most saving is $\boxed{\text{December}}$
