Answer

To find the average number of pencils that A, B, and C have, we can follow these steps:

### Step 1: Identify the number of pencils each person has.
- A has 8 pencils.
- B has 10 pencils.
- C has 15 pencils.

### Step 2: Calculate the total number of pencils.
To find the total number of pencils, we add the number of pencils each person has:
\[ \text{Total pencils} = A + B + C = 8 + 10 + 15 \]

### Step 3: Perform the addition.
Now, we will add the numbers:
\[ 8 + 10 = 18 \]
\[ 18 + 15 = 33 \]
So, the total number of pencils is 33.

### Step 4: Count the number of people.
There are 3 people (A, B, and C).

### Step 5: Calculate the average.
The average number of pencils is calculated by dividing the total number of pencils by the number of people:
\[ \text{Average} = \frac{\text{Total pencils}}{\text{Number of people}} = \frac{33}{3} \]

### Step 6: Perform the division.
Now, we will divide:
\[ \frac{33}{3} = 11 \]

### Final Answer:
The average number of pencils with A, B, and C is 11.
