Josh had 100 gummy bear candies. He decided to give his 3 siblings 10 candies each. Then he gave half of the remaining candies to his best friend. If he only wants to eat 16 gummy bear candies, how many candies are left to be shared with others? Let's think first. Chain of thought:
Josh gave a total of 3 x 10 = 30 candies to his siblings. He was then left with 100 - 30 = 70 candies. He gave 70 / 2 = 35 candies to his best friend. So he had 70 - 35 = 35 candies left. Since he only wants to eat 16 candies, there are still 35 - 16 = 19 candies left to be shared with others.
Therefore, the answer is 19.
