Felicity, Rainbow, Prudence and Bob, the unicorn friends, are prancing around in the forest. They notice seven bees and five cockroaches, and in the trees they spot eight spiders. There are also three deer and four boars. Behind a bush, they can see a pair of antlers. How many legs do all the numbered beasts combined amount to?

Answer: OPTION BStep-by-step explanation: There are seven bees. Each bee has 6 legs. Then: [tex]legs_{(bees)}=7*6=42[/tex] There are five cockroaches and each has 6 legs. So:  [tex]legs_{(cockroaches)}=5*6=30[/tex] Since there are eight spiders and we know that each has 8 legs:  [tex]legs_{(spiders)}=8*8=64[/tex] There are three deers, but the exercise says that there are  a pair of antlers begind a bush and this is a characteristic ruminant mammals. Since deers are ruminant mammals, we can say that there are 4 deers. A deer has 4 legs. Then: [tex]legs_{(deers)}=4*4=16[/tex]Since there are four boars and each has 4 legs, we know that: [tex]legs_{(boars)}=4*4=16[/tex] We know that a unicorn has 4 legs, and Felicity, Rainbow, Prudence and Bob are unicorns, then: [tex]legs_{(unicorns)}=4*4=16[/tex] Therefore, the total amount of legs of all those beasts is: [tex]total\ legs=42+30+64+16+16+16=184[/tex]
