Q: Gina had $400. She gave 1/4 of her money to her mom, used 1/8 of her money to buy clothes, gave 1/5 of her money to a charity, and kept the remaining money. How much did Gina keep?
A: Gina's mom received 1 / 4 x $400 = $100. She used 1 / 8 x $400 = $50 to buy clothes. She gave 1 / 5 x $400 = $80 to a charity. Thus, she spent a total of $100 + $50 + $80 = $230. Therefore, Gina kept $400 - $230 = $170. The answer is 170.
Question: Annie has some money. The restaurant next door sells hamburgers for $4 each. The restaurant across the street sells milkshakes for $5 each. Annie buys 8 hamburgers and 6 milkshakes. She has $70 left. How much money, in dollars, did Annie have at first?
Answer: Annie spends 4 * 8 = 32 dollars on hamburgers. Annie spends 5 * 6 = 30 dollars on milkshakes. Annie spends 32 + 30 = 62 dollars on hamburgers and milkshakes. Annie had 62 + 70 = 132 dollars at first. The answer is 132.
[Question]Archibald eats 1 apple a day for two weeks. Over the next three weeks, he eats the same number of apples as the total of the first two weeks. Over the next two weeks, he eats 3 apples a day. Over these 7 weeks, how many apples does he average a week?
[Answer]He ate 14 apples the first two weeks because 14 x 1 = 14. He ate 14 apples in the next three weeks because 14 = 14. He ate 42 apples in the final two weeks because 14 x 3 = 42. He ate 70 apples in total. He averaged 10 apples a week because 70 / 7 = 10. The answer is 10.
Q: Drew is reseeding his lawn with grass seed. One bag of grass seed covers 250 square feet of lawn. His lawn is 22 feet from the house to the curb and 36 feet from side to side. He bought four bags of seed. How many extra square feet could the leftover grass seed cover after Drew reseeds his lawn?
A: Drew’s lawn is 22 * 36 = 792 square feet. He bought enough grass seed to cover 250 * 4 = 1000 square feet. Thus, the leftover grass seed can cover 1000 - 792 = 208 square feet. The answer is 208.
Question: Suzanne wants to raise money for charity by running a 5-kilometer race. Her parents have pledged to donate $10 for her first kilometer and double the donation for every successive kilometer. If Suzanne finishes the race, how much money will her parents donate?
Answer: For the 2nd kilometer, the donation will be $10 * 2 = $20. For the 3rd kilometer, the donation will be $20 * 2 = $40. For the 4th kilometer, the donation will be $40 * 2 = $80. For the final kilometer, the donation will be $80 * 2 = $160. For the entire race the donation will be $10 + $20 + $40 + $80 + $160 = $310. The answer is 310.
Q: In Alaska the commercial Cod fishing season runs from January 1 - August 1 lasting exactly 7 months, or 213 days on a non-leap year. Two fishermen are competing against each other to see who can earn more profit. The first fisherman plans to catch fish at a steady rate of 3 per day for the entire season. The second fisherman is a novice who will need to start more slowly. He plans to catch only 1 fish per day during the first 30 days, 2 fish per day during the next 60 days, and then 4 fish per day during the remainder of the season. At the end of the season, how many more fish will be caught by the fisherman who catches the higher number of fish?
A:
The first fisherman will catch 3 * 213 = 639 fish during the season. The second fisherman catch 1 * 30 + 2 * 60 = 150 fish during the first 90 days of the season. Then, during the remaining 213 - 90 = 123 days of the season, the second fisherman will can an additional 4 * 123 = 492 fish. Thus, the second fisherman will catch a total of 150 + 492 = 642 fish. Therefore, the second fisherman will catch 642 - 639 = 3 more fish than the first fisherman at the end of the season. The answer is 3.
