Question: Bella, Monica, and Rachel are friends who like jewelry. Bella has 10 earrings, which is 25% of Monica's earrings, and Monica has twice as many earrings as Rachel. How many earrings do all of the friends have?
Answer: Bellas has 100% / 25% = 4 times less earrings than Monica. This means that Monica has 10 * 4 = 40 earrings. Rachel has two times fewer earrings than Monica, which means 40 / 2 = 20 earrings. So all three friends, have a total of 10 + 40 + 20 = 70 earrings. The answer is 70.

A: The total cost of the paintbrush, the paints, and the wooden easel is $1.50 + $4.35 + $12.65 = $18.50. Albert needs $18.50 − $6.50 = $12 more. The answer is 12.
Question: Mrs. Lim milks her cows twice a day. Yesterday morning, she got 68 gallons of milk and in the evening, she got 82 gallons. This morning, she got 18 gallons fewer than she had yesterday morning. After selling some gallons of milk in the afternoon, Mrs. Lim has only 24 gallons left. How much was her revenue for the milk if each gallon costs $3.50?
Answer: Mrs. Lim got 68 gallons - 18 gallons = 50 gallons this morning. So she was able to get a total of 68 gallons + 82 gallons + 50 gallons = 200 gallons. She was able to sell 200 gallons - 24 gallons = 176 gallons. Thus, her total revenue for the milk is $3.50 / gallon x 176 gallons = $616. The answer is 616.
[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.
