Brianna buys 5 bottles of cranberry juice at the corner store for a total cost of $2.80. If each bottle costs the same amount, how much is 10 bottles of juice?

If Brianna buys 5 bottles for $2.80, each bottle costs $2.80/5 = $<<2.80/5=0.56>>0.56

If each bottle costs $0.56, 10 bottles will cost $0.56*10 = $<<0.56*10=5.60>>5.60. Answer: \boxed{5.60}.
