Jan is making candy necklaces for herself and a few friends. Everyone receives a candy necklace each and each candy necklace is made up of 10 pieces of candies. The pieces of candies come from blocks of candy, which each produce 30 pieces of candy. If Jan breaks down 3 blocks of candy and every single piece of candy from this is used in the candy necklaces, how many friends receive a candy necklace? Let's be accurate as possible.
There are a total of 3 blocks of candy * 30 pieces of candy per candy block = 90 pieces of candy. Using this, Jan can create 90 pieces of candy / 10 pieces of candy per candy necklace = 9 candy necklaces. As Jan is keeping a candy necklace too, there must have been enough candy necklaces for 9 candy necklaces – 1 candy necklace for Jan = 8 friends.
The answer: 8.
