Question

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

Answer 1

multiply quantity of each and add them together to get total of 540

2s + 5c = 540 or 5c + 2s = 540

The difference in pages is 19 so you would subtract: c-s = 10

answer would be

d: c-s = 10

5c + 2s = 540
