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?
The total cost of the dictionary, the dinosaur book, and the cookbook is $5 + $11 + $5 = $<<5+11+5=21>>21.
Emir needs $21 − $19 = $2.
