Alex makes luxury dresses out of silk. Each dress needs 5 meters of silk and Alex has 600 meters of silk in storage. His friends also want to learn how to make these dresses so Alex gives all 5 of them 20 meters of silk each. He uses the rest to make dresses himself. How many dresses can Alex make? Give me reasons, before answering the question

Alex gives his friends a total of 5 friends * 20 meters of silk = 100 meters of silk. This means he has 600 – 100 = 500 meters of silk left in storage. He can therefore make 500 meters of silk / 5 meters of silk per dress = 100 dresses. So the final answer is 100.
