Q: To try to get the class to eat more vegetables, the teacher says that she will start giving them good character points that the class can redeem for a movie day if they earn enough. The students need to earn 200 points to win the movie day. Each time a student eats their vegetables at lunch she gives the student 2 points. There are 25 students in the class. If they have two school weeks, otherwise known as 10 days to win the movie, what is the average number of vegetables each student must eat per school week to get a movie day?
A: The students need eat 100 vegetables in total because 200 / 2 = 100. Each student needs to eat on average 4 vegetables because 100 / 25 = 4. Each student needs to eat 2 vegetables per school week because 4 / 2 = 2. The answer is 2.
Question: If two piles of toys added together make 120 toys in total, and the larger of the two piles is twice as big as the smaller one, how many toys are in the larger pile?
Answer: First, we set up the equation 3x = 120, dividing both sides by three to find that x = 40. Then we multiply X by 2 to find that 40 * 2 = 80. As 80 / 2 = 40, and 40 + 80 = 120, we find the sizes of the two piles as the larger pile is twice as big as the smaller pile, confirming that 80 is the answer. The answer is 80.
[Question]Ethan is reading a sci-fi book that has 360 pages. He read 40 pages on Saturday morning and another 10 pages at night. The next day he read twice the total pages as on Saturday. How many pages does he have left to read?
[Answer]Ethan read a total of 40 pages + 10 pages = 50 pages on Saturday. On the next day, he read a total of 50 pages x 2 = 100 pages. The total number of pages that Ethan had read is 50 pages + 100 pages = 150 pages. Therefore, Ethan has 360 pages - 150 pages = 210 pages left to read. The answer is 210.
Q: John buys 3 puzzles. The first puzzle has 1000 pieces. The second and third puzzles have the same number of pieces and each has 50% more pieces. How many total pieces are all the puzzles?
A: The second puzzle has 1000 * .5 = 500 more pieces than the first. So it has 1000 + 500 = 1500 total pieces. That means those two puzzles have 1500 * 2 = 3000 pieces. So in total there were 3000 + 1000 = 4000 pieces. The answer is 4000.
Question: Marcia needs to add 3 skirts, 2 pairs of pants and 5 blouses to her work wardrobe. A department store is offering a sale on pants; buy 1 pair get 1 pair 1/2 off. If her skirts are $20.00 each, the blouses are $15.00 and both pairs of pants are $30.00 each. How much will she spend on her wardrobe?
Answer: The pants are $30.00 and are buy one get one 1 / 2 off so the second pair will be 30 * .5 = $15.00. The first pair of pants is $30.00 and the second pair is $15.00 so the pants cost 30 + 15 = $45.00. The skirts are $20.00 each and she's buying 3 so that's 20 * 3 = $60.00. The blouses are $15.00 each and she's buying 5 so that's 15 * 5 = $75.00. All total, her wardrobe will cost $45 for the pants, $60 for the skirts and $75 for the blouses so 45 + 60 + 75 = $180.00. The answer is 180.
Q: A bar of steel weighs twice the mass of a bar of tin. If a steel bar also weighs 20 kgs more than a copper bar and a copper bar weighs 90 kgs, calculate the total weight of a container with 20 bars of each type of metal.
A:
The total weight of 20 bars of copper is 20 * 90 = 1800kgs. If a copper bar weighs 90 kgs, and a steel bar weighs 20 kgs more than a copper bar, the weight of a steel bar is 90 + 20 = 110 kgs. If a bar of steel weighs 110 kgs, 20 bars will weigh 20 * 110 = 2200kgs. The total weight of 20 bars of copper and steel is 2200 + 1800 = 4000 kgs. A bar of steel weighs twice the mass of a bar of tin, meaning a bar of tin weighs 110 / 2 = 55 kgs. The total weight of 20 bars of tins is 55 * 20 = 1100 kgs. The total weight of 20 bars of each metal is 4000 + 1100 = 5100 kgs. The answer is 5100.
