Q: Genevieve is a computer programmer working on information security software. She has written 4300 lines of code so far. Every 100 lines of code, she debugs the program. If each debugging only finds three errors, and Genevieve fixes the errors each time before proceeding, how many errors has she fixed so far?
A: Genevieve has debugged the program 4300 / 100 = 43 times. Thus, she has fixed 43 * 3 = 129 errors so far. The answer is 129.
Question: Hattie and her friend Lorelei are doing a jumping contest using a jumping rope. Hattie does 180 jumps in the first round, while Lorelei jumps 3/4 as many times as Hattie jumped. In the second round, Lorelei does 50 more jumps than Hattie. If Hattie managed to jump 2/3 times the number of jumps she did in the first round, calculate the total number of jumps the two did in the two rounds.
Answer: In the first round, Lorelei did 3 / 4 * 180 jumps = 135 jumps. In the second round, Hattie did 2 / 3 * 180 jumps = 120 jumps, while. Lorelei did 120 jumps + 50 jumps = 170 jumps. The total number of jumps for the two in both rounds is 170 jumps + 120 jumps + 135 jumps + 180 jumps = 605 jumps. The answer is 605.
[Question]Erin is sorting through the library books to decide which ones to replace. She finds 8 less than 6 times as many obsolete books as damaged books. If she removes 69 books total, how many books were damaged?
[Answer]Let o be the number of obsolete books and d be the number of damaged books. We know that o + d = 69 and o = 6d - 8. Substituting the first equation into the second equation, we get 6d - 8 + d = 69. Combining like terms, we get 7d - 8 = 69. Adding 8 to both sides, we get 7d = 77. Dividing both sides by 7, we get d = 11. The answer is 11.
Q: James builds a 20 story building. The first 10 stories are each 12 feet tall each. The remaining floors are each 3 feet taller. How tall is the building?
A: The first 10 floors are 10 * 12 = 120 feet. There are a remaining 20 - 10 = 10 stories. They are each 12 + 3 = 15 feet. So those stories are 15 * 10 = 150 feet. So the total height is 120 + 150 = 270 feet. The answer is 270.
Question: Dilan, Martha, Phillip, and Veronica went to the park together to have some fun. They all had a different number of marbles: Dilan had 14 marbles, Martha had 20 marbles, Phillip had 19 marbles and finally, Veronica had only 7 marbles. They wanted to redistribute the marbles so they each had an equal number. How many marbles did each friend have at the end of the day?
Answer: First find the total numbers of marbles: 14 + 20 + 19 + 7 = 60 marbles. After sharing them equally each person will get 60 marbles / 4 people = 15 marbles / person. The answer is 15.
Q: Francine has five full boxes of crayons and 5 loose crayons, and her friend has 27 loose crayons. They need to put all of their loose crayons in a box. How many more boxes do they need if Francine has a total of 85 crayons?
A:
Francine has 85 - 5 = 80 crayons in total that are in the boxes. Thus, each box of crayons is filled with 80 / 5 = 16 crayons. A total of 5 + 27 = 32 crayons need to be placed in the boxes. Therefore, they still need 32 / 16 = 2 boxes for the loose crayons. The answer is 2.
