Q: A taco truck is selling soft tacos for $2 and hard shell tacos for $5 during the lunch rush. The first group of customers is a family that buys four hard shell tacos and three soft tacos. The rest of the customers in the lunch rush only buy two soft tacos each. There were ten customers after the family. How many dollars did the taco truck make during the lunch rush?
A: The taco truck sold 3 + 2 * 10 = 3 + 20 = 23 soft tacos. It made 2 * 23 = $46 from soft tacos. It made 5 * 4 = $20 from hard shell tacos. Thus, the taco truck made 46 + 20 = $66 during the lunch rush. The answer is 66.
Question: The new pad of paper has 120 pages. Sammy uses 25% of the pages for his science project, and another 10 pages for his math homework. How many pages remain in the pad?
Answer: He used 0.25 * 120 = 30 on science. There were 120 - 30 = 90 pages left. And then he has 90 - 10 = 80 after math. The answer is 80.
[Question]Darnell has 1000 square feet of fabric that he's using to make mini flags. He makes square flags that are 4 feet by 4 feet, wide rectangular flags that are 5 feet by 3 feet, and tall rectangular flags that are 3 feet by 5 feet. He has already made 16 square flags, 20 wide flags, and 10 tall flags. How many square feet of fabric does he have left?
[Answer]The square flags use 16 square feet of fabric per flag because four times four equals 16. The wide flags each use 15 feet of fabric per flag because five times three equals 15. The tall flags each use 15 feet of fabric per flag because five times three equals 15. He has used 256 square feet for the square flags because 16 times 16 equals 256. He has used 300 square feet for the wide flags because 20 times 15 equals 300. He has used 150 square feet for the tall flags because ten times 15 equals 150. He has used 706 square feet because 256 plus 300 plus 150 equals 706. He has 294 square feet left because 1,000 minus 706 equals 294. The answer is 294.
Q: Elliott drew a right-angle triangle on his book. It had a base of 4 inches, a height of 3 inches and a certain length of the hypotenuse. What was the length of the perimeter of the triangle that he drew?
A: Since the hypotenuse of a triangle is found by the square root of the base squared plus the height squared. The square of the base of the first triangle is 4 * 4 = 16 square inches. The square of the height of the first triangle is 3 * 3 = 9 square inches. The sum of the squares of the base and the height of the first triangle is 16 + 9 = 25. The square root of the sum of the base and the height of the first triangle, which is the hypotenuse of the triangle, is 25 = 5 inches. Since the perimeter of a triangle is found by adding the sides of the triangle, the base and height of the triangle sum up to 3 + 4 = 7 inches. If you add the hypotenuse of the triangle the perimeter of the triangle becomes 7 + 5 = 12 inches. The answer is 12.
Question: Janet has 9 cards more than Brenda. Mara has twice as many cards as Janet. How many cards do they have in all if Mara has 40 cards less than 150?
Answer: Mara has 150 - 40 = 110 cards. Janet has 110 / 2 = 55 cards since Mara has twice as many as Janet. Brenda has 55 - 9 = 46 cards since Janet has 9 cards more than Brenda. Therefore, they all have 110 + 55 + 46 = 211 cards. The answer is 211.
Q: Tony is driving his car between his town and a friend's down. The towns are 120 miles apart and he gets there in 3 hours. The next day, he is driving to see another friend who lives 200 miles away from his friend. If he drives at the same speed, how long will the drive take?
A:
He is driving 40 MPH because 120 / 3 = 40. It will take him 5 hours because 200 / 40 = 5. The answer is 5.
