### Instruction: 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 write a Python program to solve it.### Response: # define the costs of the books
dictionary_cost = 5
dinosaur_book_cost = 11
cookbook_cost = 5

# define the amount Emir has saved
saved_money = 19

# calculate how much more money Emir needs
needed_money = dictionary_cost + dinosaur_book_cost + cookbook_cost - saved_money

# print the result
print(needed_money)
