Answer:
9 shoes per crate
Step-by-step explanation:
Number of crates of shoes on the shelf=4 crates
Since each crate must contain the same number of shoes,
Number of Shoes Per Crate
=Total Number of Shoes on the Shelf ÷ Number of Crates on the Shelf
= 36 shoes ÷ 4 crates
= 9 shoes per crate
Therefore, each crate contains 9 shoes. You drag 9 shoes into each crate to satisfy the two rules.
