[Question]Voldemort had his dinner and ate a piece of cake that has 110 calories. He also ate 1 pack of chips that contained 310 calories and drank a 500 ml bottle of coke that has 215 calories. His caloric intake for breakfast and lunch is 560 and 780 calories, respectively. If he has a 2500 calorie intake limit per day, how many calories can he still take?
[Answer]For the night he was able to intake 110 + 310 + 215 = 635 calories. For breakfast and lunch, he was able to intake 560 + 780 = 1340 calories. So, for the entire day Voldemort was able to intake 1340 + 635 = 1975 calories. Therefore, he can still intake 2500 - 1975 = 525 calories. The answer is 525.
Q: Matt has 8 baseball cards worth $6 each. If he trades two of them to Jane in exchange for 3 $2 cards and 1 $9 card, how much profit does he make?
A: First find the value of the 2 cards Matt trades: $6 / card * 2 cards = $12. Then find the total value of the 3 $2 cards: 3 cards * $2 / card = $6. Then subtract the value of the cards Marcus gave up from the value of the cards he gained to find his profit: $9 + $6 - $12 = $3. The answer is 3.
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.
Q: Mark spent 220 dollars to fix his car. It needed two parts that cost 20 dollars each, and labor cost .5 dollars a minute. How many hours did the mechanic work?
