A new spiral notebook contains 10 fewer sheets than a new
composition book. The total number of sheets of paper in
2 new spiral notebooks and 5 new composition books is
540. Which system of equations can be used to find s, the
number of sheets of paper in one new spiral, and c, the
number of sheets in one new composition book?

s - c = 10
2s – 5c = 540

c - s = 10
2c + 5s = 540

S + c= 540
2s - 5c = 10

c - s = 10
5c + 2s = 540
