Mark has kangaroos and goats. Kangaroos have two legs and goats have four legs. If he has 23 kangaroos and three times as many goats as kangaroos what is the total number of legs of all his animals? Let's be accurate as possible.
His kangaroos have a total of 23 * 2 = 46 legs. He has 23 * 3 = 69 goats. The goats have 69 * 4 = 276 legs. So in total his animals have 276 + 46 = 322 legs.
The answer: 322.
