[Question]Jim buys a wedding ring for $10,000. He gets his wife a ring that is twice that much and sells the first one for half its value. How much is he out of pocket?
[Answer]The second ring cost 2 * 10000 = $20,000. He sells the first ring for 10,000 / 2 = $5000. So he is out of pocket 10000 - 5000 = $5000. So that means he is out of pocket 20,000 + 5000 = $25,000. The answer is 25000.
Q: Sienna gave Bailey half of her suckers. Jen ate half and gave the rest to Molly. Molly ate 2 and gave the rest to Harmony. Harmony kept 3 and passed the remainder to Taylor. Taylor ate one and gave the last 5 to Callie. How many suckers did Jen eat?
A: Taylor received 5 + 1 = 6 suckers. Harmony was given 3 + 6 = 9 suckers. Molly received 9 + 2 = 11 suckers from Jen. Jen originally had 11 * 2 = 22 suckers. Jen ate 22 – 11 = 11 suckers. The answer is 11.
Question: Rick has just celebrated his 15th birthday. His oldest brother is twice his age, and his middle brother is a third of the oldest brother’s age. The smallest brother is half the middle brother’s age. If the youngest brother is 2 years younger than the smallest brother, how old, in years, is the youngest brother?
Answer: Rick’s oldest brother is 15 years * 2 = 30 years old. This means the middle brother is 30 years / 3 = 10 years old. The smallest brother is therefore 10 years / 2 = 5 years old. So the youngest brother is 5 years – 2 years = 3 years old. The answer is 3.
[Question]Mark builds an apartment that is 16 by 10 feet. There are 6 rooms in total. All the rooms are the same size except the living room which is as big as 3 other rooms. How big is the living room?
[Answer]Total square footage is 16 * 10 = 160 square feet. . There are 3 + 3 = 6 rooms. 6 - 1 = 5 of them are the same size. If x is the size of the normal room then the square footage of all rooms is 5x + 3x = 8x. So each room is 160 / 8 = 20 square feet. So the living room is 20 * 3 = 60 square feet. The answer is 60.
Q: Ben has two brothers. They can each eat 12 slices of pizza. They are ordering pizza for the night and want to make sure they get enough. The large pizzas have 14 slices and the small pizzas have 8. If they order 1 small pizza, how many large pizzas do they need to order?
A: They need 36 slices because 3 x 12 = 36. After ordering the small, they need 28 slices because 36 - 8 = 28. They need 2 large pizzas because 28 / 14 = 2. The answer is 2.
Question: Ann, Becky, and Julia are working at a pharmacy, every day for 8 hours. Each of them is providing service to 7 customers per hour. One day Julia had to finish her work earlier, so she was working only for 6 hours. How many customers did all three of these women serve that day in total?
Answer:
Ann and Becky have worked for 8 hours each, so both of them worked for 2 people * 8 hours / person = 16 hours. All three of them, including Julia, were working for 16 hours + 6 hours = 22 hours. So in total, they all have served 7 customers / hour * 22 hours = 154 customers in one day. The answer is 154.
