Borgnine wants to see 1100 legs at the zoo. He has already seen 12 chimps, 8 lions, and 5 lizards. He is next headed to see the tarantulas. How many tarantulas does he need to see to meet his goal? Think carefully first, then make a decision:
He has seen 48 chimp legs because 12 x 4 = 48. He has seen 32 lion legs because 8 x 4 = 32. He has seen 20 lizard legs because 5 x 4 = 20. He has seen 100 total legs because 48 + 32 + 20 = 100. He has to see 1000 tarantulas legs because 1100 - 100 = 1000. He has to see 125 tarantulas because 1000 / 8 = 125. So, the answer is 125.
