Question: Every year, Mabel gets as many quarters as she is years old. She always puts these and nothing else in a piggy bank. When she turns 7, how much money is in the bank?
Answer: On her second birthday she adds $.5 because 2 x .25 = .5. On her third birthday she adds $.35 because 3 x .25 = .75. On her fourth birthday she adds $1 because 4 x .25 = 1. On her fifth birthday she adds $1.25 because 5 x .25 = 1.25. On her six birthday she adds $1.5 because 6 x .25 = 1.5. On her seventh birthday she adds $1.75 because 7 x .25 = 1.75. The total is $7 because .25 + .5 + .75 + 1 + 1.25 + 1.5 + 1.75 = 7. The answer is 7.
[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.
Q: Sally needs to make a tablecloth that measures 102 inches by 54 inches. She also needs to make 8 napkins that are 6 by 7 inches. How many square inches of material will Sally need to make the tablecloth and the 8 napkins?
A: Tablecloth = 102 * 54 = 5508 square inches. Napkins = 8 * (6 * 7) = 336 square inches. 5508 + 336 = 5844 square inches. Sally will need 5844 square inches of material to make the tablecloth and 8 napkins. The answer is 5844.
Question: Joe and Adam built a garden wall with three courses of bricks. They realized the wall was too low and added 2 more courses. If each course of the wall had 400 bricks, and they took out half of the bricks in the last course to allow easy checkup of the garden, calculate the total number of bricks the wall has.
Answer: When they added two more courses for the wall, the number of courses became 3 + 2 = 5. Since each course has 400 bricks, the total number of bricks for 5 courses is 5 * 400 = 2000. To allow for an easy checkup of the wall, they removed 1 / 2 * 400 = 200 bricks from the last course of the wall. In total, the wall has 2000 - 200 = 1800 bricks. The answer is 1800.
[Question]A restaurant makes 40 more pizzas than hot dogs every day. If the restaurant makes 60 hot dogs every day, how many pizzas and hot dogs will it make in June?
[Answer]If the restaurant makes 60 hot dogs and 40 more pizzas than hot dogs every day, it makes 60 + 40 = 100 pizzas. The total number of pizzas and hot dogs it makes in a day is 100 + 60 = 160. In June, with thirty days, the restaurant will make 30 * 160 = 4800 pizzas and hot dogs in total. The answer is 4800.
[Question]Ross takes 17 breaths per minute by inhaling 5/9 liter of air to his lungs. What is the volume of air inhaled in 24 hours?
[Answer]
We have 60 minutes per hour. So, in 24 hours we have 60 * 24 = 1440 minutes. So, the volume of air Ross inhaled in 24 hours is: 17 breaths / minute * 5 / 9 L / breath * 1440 minutes = 122400 / 9 = 13600 liters. The volume of air inhaled is 13600 liters. The answer is 13600.
