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?
Let's think step by step below.
125
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.

.

The answer is 125
