Bob needs to mix 2 cups of liquid lemonade. Concentrate with 3.5 cups of water to make lemonade. Bob has 6 cups of lemonade concentrate, how much lemonade can he make?

Answer 1

To make lemonade, Bob needs to mix 2 cups of concentrate with 3.5 cups of water. This means that for every 2 cups of concentrate, he can make 5.5 cups of lemonade (2 cups of concentrate + 3.5 cups of water).

If Bob has 6 cups of concentrate, he can make 6/2 = <<6/2=3>>3 batches of lemonade.
Each batch of lemonade is 5.5 cups, so Bob can make 3 * 5.5 = <<3*5.5=16.5>>16.5 cups of lemonade. Answer: \boxed{16.5}.
