[Question]Emily loves to have pets and for that reason, she has 4 dogs in her home. Each one eats 250 grams of food per day. She has to go on vacation for 14 days. How many kilograms of food should she buy for her 4 dogs so they don't starve while she is out?
[Answer]Each dog would eat 250 grams so 4 will would eat 4 x 250 grams = 1000 grams of food per day. 1.000 grams is equal a 1 kilogram. Emily is going on vacation for 14 days and with the 4 dogs together eating 1 kilogram of food per day, 14 days x 1 kg of food / day = 14 kg of food would be enough for two weeks. The answer is 14.
Q: Beckett is 12 and is three years younger than Olaf, while Shannen is two years younger than Olaf. If Jack is five more than twice as old as Shannen, what is the sum of the ages of all 4 people?
A: Olaf is 12 years + 3 years = 15 years old. Shannen is 15 years old - 2 years = 13 years old. Jack is 5 years + (2 * 13 years) = 31 years old. The sum of all of their ages is 12 + 15 + 13 + 31 = 71 years old. The answer is 71.
Question: Bobby needed to make some trips with his truck and had only 12 gallons of gasoline. He drives to a supermarket 5 miles away and then drives back home. Then he headed to his farm which was 6 miles away. Two miles into the journey, he turned around and drove back home to retrieve some farming tools he forgot to take earlier and drove down to the farm. If he now has exactly 2 gallons of gasoline left, at what rate in miles per gallon has his truck been consuming gasoline?
Answer: The trip to the supermarket and back home covers 5 + 5 = 10 miles. The round trip of two miles each before he actually went to the farm covers 2 + 2 = 4 miles. Six miles to the farm and the total mileage is 10 + 4 + 6 = 20 miles. The truck consumed 12 - 2 = 10 gallons of gasoline for the total journey. So, the rate is 20 / 10 = 2 miles per gallon. The answer is 2.
[Question]Steve owns a lake shop that sells fish. He has a stock of 200 fish. He sells 50 fish and because his refrigerators stop working a third of the remaining fish become spoiled. A new stock of 200 more fish arrives. How many fish does he have in stock now?
[Answer]If he had 200 fish and sells 50, he is left with 200 - 50 = 150 fish. If a third of them get spoiled 1 / 3 * 150 = 50 fish get spoiled. The remaining number of fish is now 150 - 50 = 100. He then gets 200 more to make 100 + 200 = 300 fish. The answer is 300.
[Question]Erica lives near a lake where most locals sell fish as their main source of income, earning $20 per kg of fish. She goes out fishing today and catches twice as many fish as she caught in total in the past four months. If Erica trawled 80 kg of fish in the past four months, not including today, how much money will she have earned in the past four months including today (assuming she sells all her fish)?
[Answer]
In the past four months, not including today, Erica has 80 kg * $20 / kg = $1600 worth of fish. Today, Erica trawled 80 * 2 = 160 kg of fish. Thus today's earnings are 160 kg * $20 / kg = $3200. Her total earnings are $3200 + $1600 = $4800. The answer is 4800.
