Calculate the index number for the total cost of the raw material uses, given `Sigma omega=10 and Sigma I omega= 1173.61`.

Answer

To calculate the index number for the total cost of the raw material usage, we will follow these steps:

### Step 1: Write down the given values
We have the following values:
- \(\Sigma W = 10\)
- \(\Sigma IW = 1173.61\)

### Step 2: Use the formula for the index number
The formula for calculating the index number \(I\) is given by:

\[ I = \frac{\Sigma IW}{\Sigma W} \]

### Step 3: Substitute the given values into the formula
Now, we will substitute the values we have into the formula:

\[ I = \frac{1173.61}{10} \]

### Step 4: Perform the division
Now, we will perform the division:

\[ I = 117.361 \]

### Step 5: Write the final answer
Thus, the index number for the total cost of the raw material usage is:

\[ \text{Index Number} = 117.361 \]
