The Master Chief collects spiders and starfish. If his spiders have 8 legs and his starfish have 5 legs, how many starfish must he have given that his spider/starfish collection totals 19 creatures and 116 legs?
Let s be the number of starfish. So, there must be 19-s spiders. We count up legs: 5s+8(19-s)=116. This gives 5s+152-8s=116, or 36=3s. So, the Chief has 12 starfish.
