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? Give the rationale and then the answer.
Let's think step by step. Let x be the number of animals in the Rain Forest exhibit. 3x - 5 = 16. 3x = 21. x = 7.. The answer is: 7.

During the holidays, Lance works as a merchandiser. He works 35 hours a week, spread equally over 5 workdays. If Lance earns $9 an hour, how much does he make on each workday? Give the rationale and then the answer.
Let's think step by step. Lance works 35 / 5 = 7 hours a day. So he makes $9 x 7 = $63 on each workday.. The answer is: 63.

If a tarantula has eight legs, and one tarantula egg sac can contain 1000 tarantulas, how many baby tarantula legs would be in one less than 5 egg sacs? Give the rationale and then the answer.

Let's think step by step. One less than 5 is 5 - 1 = 4. If one tarantula egg sac can contain 1000 tarantulas, then four egg sacs can hold 4 * 1000 = 4000 tarantula babies. If each tarantula baby has eight legs, the 4 egg sacs can contain 4000 * 8 = 32,000 baby tarantula legs.. The answer is: 32000.
