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?
How many meters of silk does Alex give to his friends? ** Alex gives his friends a total of 5 friends * 20 meters of silk = <<5*20=100>>100 meters of silk.
How many meters of silk does Alex have left in storage? ** This means he has 600 – 100 = <<600-100=500>>500 meters of silk left in storage.
How many dresses can Alex make? ** He can therefore make 500 meters of silk / 5 meters of silk per dress = <<500/5=100>>100 dresses.
