Safari National park has 100 lions, half as many snakes, and 10 fewer giraffes than snakes. On the other hand, Savanna National park has double as many lions as Safari National park, triple as many snakes as Safari National park, and 20 more giraffes than Safari National park. How many animals in total does Savanna National park have? Think carefully first, then make a decision:
Safari National park has 1 / 2 * 100 = 50 snakes. Safari National park has 50 - 10 = 40 giraffes. Savanna National park has 100 * 2 = 200 lions. Savanna National park has 50 * 3 = 150 snakes. Savanna National park has 40 + 20 = 60 giraffes. Savanna National park has a total of 200 + 150 + 60 = 410 animals. So, the answer is 410.
