Question

Jose, Thuy, and Kareem each start with the number 10. Jose subtracts 1 from the number 10, doubles his answer, and then adds 2. Thuy doubles the number 10, subtracts 1 from her answer, and then adds 2. Kareem subtracts 1 from the number 10, adds 2 to his number, and then doubles the result. Who gets the largest final answer?

Accepted Answer

Jose gets 10 - 1 = 9, then 9 2 = 18, then 18 + 2 = 20. Thuy gets 10 2 = 20, then 20 - 1 = 19, and then 19 + 2 = 21. Kareem gets 10 - 1 = 9, then 9 + 2 = 11, and then 11 2 = 22. Thus, Kareem gets the highest number, and the answer is Kareem.
