Emir wants to buy a dictionary that costs $5, a dinosaur book that costs $11, and a children's cookbook that costs $5. He has saved $19 from his allowance. How much more money does Emir need to buy all three books? Let's think first. Chain of thought:
The total cost of the dictionary, the dinosaur book, and the cookbook is $5 + $11 + $5 = $21. Emir needs $21 − $19 = $2.
Therefore, the answer is 2.
