Answer:
Mr.Riley collected $376.
Explanation:
First it says there are 1692 cookies and 36 boxes. When you put 1692 cookies into 36 boxes its the same thing as 1692 divided by 36 which is 47.
Then it says each box cost $8. So there are 47 cookies in 36 boxes and each box cost $8 which is the same as multiplying 47 by 8 which is $376.
