Give the step-by-step reasoning process and then the final answer. Haley has 5 more necklaces than Jason. Josh has half the number of necklaces as Jason. If Haley has 25 necklaces, how many more necklaces does Haley have than Josh?
Jason has 25 - 5 = 20 necklaces. Josh has 20 / 2 = 10 necklaces. Haley has 25 - 10 = 15 more necklaces than Josh.
The final answer: 15.
