I do B/A school and originally charged $15/day, now raised to $17. The school next door is $20, and I offer a healthy snack included, so I think $17 is reasonable. I do pickups and drop-offs, will pick up early for weather closures (I have 2 kids in the school myself, so it makes sense) and offer full-day care on all PA days and summer breaks.

I am considering switching to all B/A school at the end of next year, as we may be expecting in April (just waiting to confirm it! - sorry, TMI) and upping to $20/day. If I do that though, I may have to offer breakfast too to get the clients, and I really don't want to do that - cereal and milk are expensive! That's the problem with older kids; they can eat a ton! One of the reasons I raised from $15 to $17, just to help cover their food.

Like mickyc said, it depends on what you offer and what else is around. Our school offers care, but it has very limited spots, limited hours, and high fees, so I think I may be ok in finding kids. Especially if I offer homework help, I think. If your area has lots of affordable options though, it may be tougher.
