[Question]It will cost $60 to rent a sailboat and $80 per hour to rent a ski boat. Ken rented a sailboat while Aldrich rented a ski boat. How much more did it cost Aldrich to rent the ski boat than Ken to rent a sailboat for three hours a day in two days?
[Answer]Ken paid $60 x 3 = $180 to rent a sailboat for 3 hours in a day. Aldrich paid $80 x 3 = $240 to rent a ski boat in 3 hours in a day. So Aldrich paid $240 - $180 = $60 more to rent a ski boat than Ken to rent the sailboat each day. Therefore, it cost Aldrich $60 x 2 = $120 more to rent a ski boat than Ken to rent the sailboat in two days. The answer is 120.
Q: A store is comparing their profits throughout the year. They had profits of $1,500 in the first quarter of the year, $3,000 in the third quarter, and $2,000 in the fourth quarter. If their annual profits are $8,000, how much profit, in dollars, did they make in the second quarter?
A: In the three quarters we have figures for, the store made a total of $1500 + $3000 + $2000 = $6,500. Subtracting this from their annual profit shows that they made $8000 – $6500 = $1,500 profit in the second quarter. The answer is 1500.
Question: A soccer ball takes twenty minutes to inflate. Alexia and Ermias are inflating balls, with Alexia inflating 20 balls and Ermias inflating 5 more balls than Alexia. Calculate the total time in minutes they took to inflate all the soccer balls.
Answer: To inflate a soccer ball, it takes 20 minutes, and if Alexia inflated 20 soccer balls, she took 20 * 20 = 400 minutes. Ermias has 5 more soccer balls than Alexia, meaning she has a total of 20 + 5 = 25 soccer balls. If each soccer ball takes 20 minutes to inflate, Ermias took 25 * 20 = 500 minutes to inflate all the soccer balls she had. Alexia and Ermias took 400 + 500 = 900 minutes to inflate all the soccer balls. The answer is 900.
[Question]Milo is making a giant loaf of bread, and the recipe calls for pounds of eggs instead of telling him the number. He needs 6 pounds in total. He looks up online that an egg weighs 1/16 of a pound. If he needs 6 pounds of eggs, how many dozen should he buy?
[Answer]If one egg weighs 1 / 16 of a pound then 1 pound will be made up of 1 / (1 / 16) = 16 eggs. One pound of eggs is 16 eggs so 6 pounds is 6 * 16 = 96 eggs. One dozen is 12 eggs so 96 eggs will make 96 / 12 = 8 dozens. The answer is 8.
Q: Last year, Jorge planted corn on all of his 60 acres of property. Typically, corn grown on good soil yields 400 bushels per acre, but in clay-rich soil, the yield is only half as much per acre as in good soil. One-third of Jorge's 60 acres of land is clay-rich soil and the rest is good soil. How many bushels of corn did Jorge's land yield last year?
A: Jorge has 60 * (1 / 3) = 20 acres of clay - rich soil. He has 60 - 20 = 40 acres of good soil. At 400 bushels per acre, his 40 acres of good soil produced 40 * 400 = 16,000 bushels of corn. If good soil produces 400 bushels per acre, clay - rich soil produces 400 / 2 = 200 bushels per acre. At 200 bushels per acre, his 20 acres of clay - rich soil produced 20 * 200 = 4,000 bushels of corn. Altogether, his land produced 16,000 + 4,000 = 20,000 bushels of corn. The answer is 20000.
Question: Libby is building an igloo in her backyard using bricks of snow. She builds her igloo in rows, using a total of 10 rows of bricks of snow. The bottom half of the igloo has 12 bricks of snow in each row while the top half of the igloo has 8 bricks of snow in each row. How many bricks of snow did Libby use for her igloo?
Answer:
In the bottom half of the igloo, there are 10 rows / 2 = 5 rows of bricks of snow. So in the bottom half of the igloo, there are 5 rows * 12 bricks of snow in each row = 60 bricks of snow. In the top half of the igloo, there are 5 rows * 8 bricks of snow in each row = 40 bricks of snow. There is therefore a total of 60 + 40 = 100 bricks of snow in the igloo. The answer is 100.
