Choice B and Choice C
====================================================
Reasoning:
c = cost of one crate (some unknown amount in dollars)
c+20 = cost of a crate and a leash
5(c+20) = cost of five sets of items mentioned
5(c+20) = 475 is one equation we can form
5c+100 = 475 is another equation we can form
I used the distributive rule to go from 5(c+20) to 5c+100.
The 100 indicates that the five leashes combine to $100, since 5*20 = 100.
The 5c represents the cost of all five crates combined.
So 5c+100 is another way to express the total cost of all five crates and all five leashes.
---------------
Side note: Solving either equation leads to c = 75, meaning that each crate costs $75.
