Give the step-by-step reasoning process and then the final answer. Monroe has a collection of ants and a collection of spiders. He has 8 spiders and 12 ants. He is wondering what the number of legs of the entire collection is.
The ants have 72 legs because 12 times 6 equals 72. The spiders have 64 legs because 8 times 8 equals 64. There are a total of 136 legs because 72 plus 64 equals 136.
The final answer: 136.
