Code challenge merge with ruby

I am trying to merge two hashes in this way:

grocery_item = { "item" => "Bread", "quantity" => 1, "brand" => "Treehouse Bread Company" } calories = { "calories" => 100 } grocery_item.merge(calories)

But it doesn't work. Would you please to help me? Thanks

hash.rb 
grocery_item = { "item" => "Bread", "quantity" => 1, "brand" => "Treehouse Bread Company" }
calories = { "calories" => 100 }
grocery_item.merge({'calories' => 100})

First the challenge asks you to assign the result to a new variable called final_item. Since the second hash is stored in the variable calories what you need to do is use that variable as an argument passed in to the merge method. Your code should look like this:

grocery_item = { "item" => "Bread", "quantity" => 1, "brand" => "Treehouse Bread Company" }
calories = { "calories" => 100 }

final_item = grocery_item.merge(calories)
