Solution
The correct option is D The amount returned after paying for the sticks Let us write a multiplication equation to find the number of sticks.
Total cost of sticks = Number of sticks × Cost of each stick
Number of sticks = Total cost of sticks ÷ Cost of each stick
Let the number of sticks be “p”.
p=$36÷$9=4sticks
We were able to calculate the number of sticks without using the amount returned after paying for the sticks. Hence, it is not needed.
