Question: There are 19 students in the 3rd grade and twice that number in the 4th grade. There are 10 boys and 19 girls in the 2nd grade. How many students are there in total?
Answer: In the third grade, there are 19 students. In the fourth grade, there are 2 × 19 = 38 students. Counting the boys and girls in the second grade, there are 10 + 19 = 29. There are 19 + 38 + 29 = 86 students in total. The answer is 86.
[Question]Michelle uses 40 beads in making a necklace. She uses 5 blue beads and 2 times as many red beads as blue beads. Then she uses the same number of white beads as the blue and red beads combined. If the rest of the beads she uses are silver, how many silver beads does she use?
[Answer]Michelle uses 5 x 2 = 10 red beads. She uses 5 + 10 = 15 white beads. So she uses a total of 5 + 10 + 15 = 30 blue, red, and white beads. Therefore, she uses 40 - 30 = 10 silver beads. The answer is 10.
Q: Fiona and Casey share the hoodies they own. Between the two of them, they own eight hoodies. Casey owns two more than Fiona. How many hoodies does Fiona own?
A: Let H be the number of hoodies Fiona owns. Casey owns H + 2 hoodies. Together, they own H + H + 2 = 2H + 2 = 8 hoodies. Thus, 2H = 8 - 2 = 6 hoodies. Therefore, Fiona owns H = 6 / 2 = 3 hoodies. The answer is 3.
Question: Abraham is buying some toiletries and creates a budget of $60 for his shopping. He buys 4 shower gels for $4 each, a tube of toothpaste for $3, and a box of laundry detergent. If he has $30 remaining in his budget, how much money, in dollars, did Abraham spend on the box of laundry detergent?
Answer: Shower gel costs Abraham 4 shower gels * $4 = $16. So the shower gel and toothpaste combined have cost him $16 + $3 = $19. He had money remaining in his budget so the total cost of his shopping must have been $60 – $30 = $30. The box of laundry detergent therefore cost him $30 – $19 = $11. The answer is 11.
[Question]Daleyza won a house construction project that involved the construction of three houses with several units. The first building was designed to have 4000 units, the second building 2/5 times as many units as the first building, and the third building was to have 20% more units than the second building. How many units were Daleyza contracted to build?
[Answer]If the first building was designed to have 4000 units, the second building, which had 2 / 5 times as many units as the first building, was to have 2 / 5 * 4000 = 1600 more units. Together, the first and the second building had to have 1600 + 4000 = 5600. The third building was to have 120 / 100 * 1600 = 1920 units. Altogether, Daleyza won a project that required her to construct 5600 + 1920 = 7520 units. The answer is 7520.
[Question]Joe buys 3 oranges, 7 juices, 3 jars of honey, and 4 plants at the market. The fruit costs $4.50 each, the juice was 50 cents each, the jars of honey were $5, and the plants were 2 for $18. How much does Joe spend at the market?
[Answer]
Joe spends 4.50 * 3 = 13.50 on oranges. Joe spends 7 * 0.5 = 3.50 on juice. Joe spends 3 * 5 = 15 on honey. Each plant costs 18 / 2 = 9 dollars. Joe spends 9 * 4 = 36 on plants. Joe spends a total of 13.50 + 3.50 + 15 + 36 = 68 dollars at the market. The answer is 68.
