The Reptile House at the zoo has 5 fewer animals than 3 times the number of animals housed in the Rain Forest exhibit. If the Reptile House has 16 animals, how many are in the Rain Forest exhibit? Think carefully first, then make a decision:
Let x be the number of animals in the Rain Forest exhibit. 3x - 5 = 16. 3x = 21. x = 7. So, the answer is 7.
