A new spiral notebook contains 30 more sheets of paper than a new memo book. The total number of sheets of paper in 3 new spiral notebooks and 5 new memo books is 810. Which system of equations can be used to find s, the number of sheets of paper in one new spiral notebook, and m, the number of sheets of paper in one new memo book?

• s − m = 30 and 3s + 5m = 810

• s + m = 30 and 3s + 5m = 810

• s − m = 30 and 5s + 3m = 810

• s + m = 30 and 5s + 3m = 810
