[Question]Jerry takes 2 antacids that weigh 2 grams each and are 5% zinc by weight. Then he takes three more smaller antacids that weigh 1 gram each and have 15% zinc. How many milligrams of zinc does he eat?
[Answer]First find the total weight of the big antacids: 2 grams / antacid * 2 antacids = 4 grams. Then convert that weight to milligrams: 4 grams * 1000 mg / gram = 4000 mg. Then multiply that number by 5% to find how much zinc is in the big antacids: 4000 mg * 5% = 200 mg. Then find the total weight of the smaller antacids in milligrams: 3 antacids * 1 gram / antacid * 1000 mg / gram = 3000 mg. Then multiply that number by the percent of zinc to find the amount of zinc in the small antacids: 3000 mg * 15% = 450 mg. Then add the zinc Jerry gets from each set of pills to find the total amount of zinc he eats: 450 mg + 200 mg = 650 mg. The answer is 650.

Question: Jocelyn bought a car 3 years ago at $4000. If the car's value has reduced by 30%, calculate the current value of the car.
Answer: If Jocelyn bought the car 3 years ago at $4000, the car's value has reduced by 30 / 100 * $4000 = $1200. The current value of the car is $4000 - $1200 = $2800. The answer is 2800.
[Question]A colony of bees can contain up to 80000 individuals. In winter they are more exposed to death, and if the winter is really cold the bees can begin to die slowly. If the colony starts to lose 1200 bees per day, how many days will pass until the number of bees in the colony reaches a fourth of its initial number?
[Answer]A fourth of the initial number of bees is 80000 bees / 4 = 20000 bees. The number of bees that has to die is 80000 bees – 20000 bees = 60000 bees. For the colony to reach a fourth of its population, 60000 bees ÷ 1200 bees / day = 50 days have to pass. The answer is 50.
