Question

Harvey has 3 pets. On Monday she uses d cans of pet food. On Tuesday she used 6 cans and wed thurs fri she uses 4 cans each day. How many cans does she use during these 3 days.

Which number is not needed to solve this problem.

4 3 5 6

And why?

Answer 1

Typo during the 5 days not 3 days

Answer 2

The sum of all the cans for the 5 days is
d + 6 + 3*4

In the above sentence I see all four numbers used. But, I guess technically the 5 is not needed, since all we have to do is add up the numbers of cans.

So, assuming d is not 5, then the 5 is n ot needed.
