Q: The size of a bathroom is 96 sq ft. If the width of the bathroom is 8 feet and the owner wants to extend it by 2 feet on each side, what is the new area of the bathroom?
A: The original length of the bathroom is 96 sq ft / 8 ft = 12 ft. The new length of the bathroom is 12ft + 2 ft = 14 ft. The new width of the bathroom is 8 ft + 2 ft = 10 ft. The new area of the bathroom is 14ft x 10 ft = 140 sq ft. The answer is 140.
Question: Jackson is buying school supplies for his third grade class, which has 30 students. Each student needs 5 pens, 3 notebooks, 1 binder and 2 highlighters. Pens cost $0.50, notebooks cost $1.25, binders cost $4.25, and highlighters cost $0.75. If Jackson gets a $100 teacher discount, how much does he spend on school supplies?
Answer: First calculate the cost of the pens for one student by multiplying the number of pens by the cost per pen: 5 pens * $0.50 / pen = $2.50. Then calculate the cost of the notebooks for one student by multiplying the number of notebooks by the cost per notebook: 3 notebooks * $1.25 / notebook = $3.75. Then calculate the cost of the highlighters for one student by multiplying the number of highlighters by the cost per highlighters: 2 highlighters * $0.75 / highlighter = $1.50. Now add the cost of all the different supplies to find the total cost for one student: $2.50 + $3.75 + $1.50 + $4.25 = $12.00. Now multiply the cost per student by the number of students to find the total cost before the discount: 30 students * $12.00 / student = $360.00. Now subtract the teacher discount to find the final cost: $360.00 - $100.00 = $260.00. The answer is 260.
[Question]Jonathan's full name contains 8 letters for the first name and 10 letters for the surname. His sister's name has 5 letters for the first name and 10 letters for the second name. What's the total number of letters in their names?
[Answer]Jonathan has 8 + 10 = 18 letters in his name. His sister has 5 + 10 = 15 letters in her name. The total number of letters in their names is 18 + 15 = 33. The answer is 33.
Q: There were 8000 jelly beans in a certain barrel, and 10 people lined up to take some. The first six people each took twice as many jelly beans as each of the last four people took. If the last four people each took 400 jelly beans, how many jelly beans remained in the container?
A: If the last four people each took 400 jelly beans, they took a total of 4 * 400 = 1600 jelly beans. The first six people each took twice as many jelly beans as each of the last four people took, meaning each of them took 2 * 400 = 800 jelly beans. The total number of jelly beans the first six people took is 800 * 6 = 4800 jelly beans. Together, all 10 people took together 4800 + 1600 = 6400 jelly beans. If there were 8000 jelly beans in a certain barrel, the number of jelly beans that remained is 8000 - 6400 = 1600. The answer is 1600.
Question: An archer needs to practice. He intends to shoot 200 shots 4 days a week. He is able to recover 20% of his arrows. The arrows he uses cost $5.5 per arrow. His team agrees to pay for 70% of the cost of his arrows. How much does he spend for arrows a week?
Answer: He shoots 200 * 4 = 800 shots per week. He can recover 800 * .2 = 160 of those arrows. So he uses 800 - 160 = 640 arrows a week. The cost for those arrows would come out to 640 * 5.5 = $3520 per week. His team pays for 3520 * .7 = $2464 of that. So he has to pay 3520 - 2464 = $1056 per week for arrows. The answer is 1056.
Q: Andy is running late. School starts at 8:00 AM and it normally takes him 30 minutes to get there, but today he had to stop for 3 minutes each at 4 red lights and wait 10 minutes to get past construction. If he left his house at 7:15, how many minutes late will he be?
A:
First find how many minute Andy had to get to school when he left his house: 8:00 AM - 7:15 AM = 45 minutes. Then find the total time he spent waiting at red lights: 3 minutes / light * 4 lights = 12 minutes. Now add the normal travel time, red light time, and construction wait time to find Andy's total travel time: 30 minutes + 12 minutes + 10 minutes = 52 minutes. Now subtract the amount of time Andy had when he left his house from that number to find how many minute late he is: 52 minutes - 45 minutes = 7 minutes. The answer is 7.
