[Question]George wants to borrow $100 from a loan shark. The finance fee starts at 5% and doubles every week. If George plans to borrow for 2 weeks, how much in fees will he have to pay?
[Answer]After the first week, the fee will be $100 * 5% = $5. For the second week, the finance percentage will be 5% * 2 = 10%. George will have to pay a fee of $100 * 10% = $10 for the second week. In total, George will be charged $5 + $10 = $15 in fees. The answer is 15.
Q: Carla needs to bring water to her animals. Each horse needs twice as much water as a pig, and the chickens drink from one tank that needs 30 gallons. How many gallons of water does Carla need to bring if she has 8 pigs and 10 horses and each pig needs 3 gallons of water?
A: First figure out how much water all the pigs need: 8 pigs * 3 gallons / pig = 24 gallons. Then figure out how much water one horse needs by multiplying a pig's needs by 2: 3 gallons * 2 = 6 gallons. Now find how much water all the horses need: 10 horses * 6 gallons / horse = 60 gallons. Finally, add up all the animals' water needs: 24 gallons + 60 gallons + 30 gallons = 114 gallons. The answer is 114.
Question: Matthew drinks 4 glasses of water per day. Each glass is 5 ounces. He decides to just buy a 35 ounces water bottle. How many times will he fill it each week?
Answer: He drinks 20 ounces of water a day because 4 x 5 = 20. The drinks 140 ounces in a week because 7 x 20 = 140. He will fill it up 4 times because 140 / 35 = 4. The answer is 4.
[Question]Michelle is bringing sandwiches to work to give to her co-workers. She gives 4 sandwiches to one of her co-workers and keeps twice this amount for herself. If she had originally made 20 sandwiches, how many sandwiches does she have left to give to her other co-workers?
[Answer]Michelle kept 4 sandwiches * 2 = 8 sandwiches for herself. This leaves 20 total sandwiches – 4 sandwiches for a coworker – 8 sandwiches for herself = 8 sandwiches for her other co - workers. The answer is 8.
Q: Nicole has 4 fish tanks. The first two tanks need 8 gallons of water each and the other two need 2 fewer gallons of water each than the first two tanks. If Nicole needs to change the water of the aquarium every week, how many gallons of water will she need in four weeks?
A: The first two tanks need 8 x 2 = 16 gallons of water. The other two tanks need 8 - 2 = 6 gallons of water each. So, the two other tanks need 6 x 2 = 12 gallons of water. Nicole needs 16 + 12 = 28 gallons of water every week for her four tanks. Therefore, she needs a total of 28 x 4 = 112 gallons of water in four weeks. The answer is 112.
Question: Randy had $3,000. Smith gave him another $200. Randy then gave Sally $1,200 and kept the rest. What was the value, in dollars, of the rest?
Answer:
After Smith gave him $200, Randy had 3000 + 200 = 3200 dollars. The value of the rest of the money is 3200 - 1200 = 2000 dollars. The answer is 2000.
