Problem:
There are 64 crayons in a deluxe box of crayons. If a school bought 35 boxes, how many total crayons were bought?
Solution:
1.
Identify the given information:
- Each box contains 64 crayons.
- The school bought 35 boxes.
2.
Determine the total number of crayons:
- To find the total number of crayons, we need to multiply the number of crayons per box by the number of boxes.
- Mathematically, this is expressed as:
\[
\text{Total crayons} = \text{Number of crayons per box} \times \text{Number of boxes}
\]
- Substituting the given values:
\[
\text{Total crayons} = 64 \times 35
\]
3.
Perform the multiplication:
- We can break down the multiplication for clarity:
\[
64 \times 35 = 64 \times (30 + 5) = (64 \times 30) + (64 \times 5)
\]
- Calculate each part separately:
\[
64 \times 30 = 1920
\]
\[
64 \times 5 = 320
\]
- Add the results:
\[
1920 + 320 = 2240
\]
4.
Verify the result:
- Double-check the multiplication to ensure accuracy:
\[
64 \times 35 = 2240
\]
5.
Match the result with the given options:
- The options provided are:
- A. 3,600
- B. 1,500
- C. 2,200
- D. 4,000
- The correct answer is
2,240, which is closest to option C (2,200).
Final Answer:
\[
\boxed{C}
\]
