Brinley's teacher took the grade six students to the San Diego Zoo to watch and learn about animals. While at the zoo, Brinley counted 100 snakes, 80 arctic foxes, and 20 leopards. She also saw ten times more bee-eaters than leopards, half as many cheetahs as snakes, and twice as many alligators as the total number of Arctic foxes and leopards. What's the total number of animals Brinley counted at the zoo? Give the rationale and then the answer.
Let's think step by step. There were 10 * 20 = 200 more bee - eaters at the zoo. There were 1 / 2 * 100 = 50 cheetahs. The total number of foxes and leopards is 80 + 20 = 100. There were 2 * 100 = 200 alligators. The total number of animals is 200 alligators + 220 bee - eaters + 100 snakes + 80 tactic foxes + 20 leopards + 50 cheetahs = 670 animals.. The answer is: 670.

Tom went to the store to buy fruit. Lemons cost $2, papayas cost $1, and mangos cost $4. For every 4 fruits that customers buy, the store offers a $1 discount. Tom buys 6 lemons, 4 papayas, and 2 mangos. How much will he pay? Give the rationale and then the answer.
Let's think step by step. For 6 lemons, Tom will pay 6 * 2 = $12. For 3 papayas, he will pay 3 * 1 = $3. For 2 mangos, he will pay 2 * 4 = $8. In total, the cost of the fruits before discount is 12 + 4 + 8 = $24. The total number of fruits is 6 + 4 + 2 = 12 fruits. For 12 fruits, Tom gets a discount of 12 / 4 = $3. Subtracting the discount offered by the store, Tom will pay 24 - 3 = $21.. The answer is: 21.

Tim host a show and they film multiple episodes per day. Each episode is 20 minutes long and it takes 50% longer than that to film each episode. Each week they show 5 episodes. How many hours would it take to film 4 weeks of episodes? Give the rationale and then the answer.
Let's think step by step. Each episode takes 20 * .5 = 10 minutes longer to film than it is. So it takes 20 + 10 = 30 minutes. They are filming 5 * 4 = 20 episodes. So it takes 20 * 30 = 600 minutes. This is equivalent to 600 / 60 = 10 hours.. The answer is: 10.
