most guys around me charge 120 a yard install , no paper.
all depends how much prep work you have to do.
I did a few big plaza's around 25 yrds, this year but consist of filling gardens with curbs so all I had to do was dump and spread. If you have to spend time edging then thats more time you have to factor in
I single yard does go that far either.
