A grocery store sells a bag of 6 oranges for $5.22. What is the cost of oranges, in dollars per orange?

To find the cost of oranges per orange, we need to divide the total cost of the bag of oranges by the number of oranges in the bag: 5.22 / 6 = $<<5.22/6=0.87>>0.87 per orange. Answer: \boxed{0.87}.
