A pad of looseleaf paper is $0.40 less than a notebook. Together they cost $1.80. How much does the looseleaf paper cost?? The notebook?

Let x = the pad of paper.
x + x  0.4 = 1.80
2x = 1.40
x = 0.70 
P + N = 1.80
N = P + .40
P +(P+ .40) = 1.80
2 P = 1.40
P = 0.70
N = P+ .40 = 1.10 
I beleive the answer is the notebook cost $1.30. and the loose leaf paper cost $0.50.

You are out voted brain :)
