The difference in cost is $2 for the extra 2 cheese buns (since w + 4 is effectively 2 greater than w + 2 no matter our choice of w).
So, one cheese bun costs $1.
Since two cheese buns cost $2, and one sandwich plus two cheese buns cost $(w + 2), one sandwich must have cost $w.
So, one cheese bun costs $1.
Since two cheese buns cost $2, and one sandwich plus two cheese buns cost $(w + 2), one sandwich must have cost $w.
