8500 sq. ft. of beds, nothing previously there so it's not like I'm just covering the old mulch so I figured for 170 sq ft. per yard equalling 50 yards for a grand total of $1980 installed, I gave what seemed to me to be a pretty damn good discount and only charging about $22 per yard for installation, when normally for just a couple yards I charge between $50 and $75 installed for double hammered mulch I get for $17 per yard. Anyway, the customer was like "wow! " But that seems like a good price to me!!!!!!!!!!!!! Anyway, my question really is how many yards would an average dump truck hold? They said they were thinking about getting a load from the city for $100 per load so I told them that the mulch the city sells is junk basically, I mean it's good for some applications like under pine needles maybe but not for decorating a house that has a golf course in the back yard! So how many yards fit in a dump?
