Answer:
Answer is D
C = (4 x 16) - 6
Explanation:
There is 4 packages. Packages can hold many cookies in this case 16 cookies can be placed inside 1 package.
The total number of cookies can be calculated:
16 x 4 (4 packages altogether with 16 cookies in each package)
They did not eat 6 cookies so 6 cookies are leftover or remaining:
(16 x 4) - 6 (subtract 6 because they did not eat it, we want what they already ate - takeaway 6)
Basically means: The Total minus The Remaining
(The Total - The Remaining)
