[Question]Jacob is trying to eat less than 1800 calories a day. If he eats 400 calories for breakfast, 900 calories for lunch, and 1100 calories for dinner, how many more calories did he eat than he planned?
[Answer]First add up the calories from all three meals: 900 + 400 + 1100 = 2400. Then subtract Jacob's goal from the number of calories he actually ate: 2400 - 1800 = 600. The answer is 600.
Q: James earns $10 per week as an allowance. After saving all his money for four weeks, he spends half of it on a new video game. He then spends a quarter of what is left to buy a new book. How much money does he have left?
A: He starts out with $10 * 4 = $40. James spend $40 / 2 = $20 on the video game. After buying the game, he has $40 - $20 = $20 left. He spent $20 / 4 = $5 on the book. He has $20 - $5 = $15 left. The answer is 15.
Question: A fox can run at the maximum speed of 50 kilometers per hour. Considering the fox would run at a constant speed, what distance would he make during 120 minutes?
Answer: 1 hour is 60 minutes, so 120 minutes is 120 / 60 = 2 hours. During one hour a fox can make 50 kilometers, so during two hours, he would be able to run 50 * 2 = 100 kilometers. The answer is 100.
[Question]Marcy is the lunch monitor in an elementary school cafeteria. She gives 5 time-outs for running, 1 less than five times that number of time-outs for throwing food, and 1/3 the number of food-throwing time-outs for swearing. If each time-out is 5 minutes, how much time do the students spend in time-out total?
[Answer]First multiply the number of running time - outs by 5: 5 time - outs * 5 = 25 time - outs. Then subtract 1 from that number to find the number of food - throwing time - outs: 25 time - outs - 1 = 24 time - outs. Then divide that number by 3 to find the number of swearing time - outs: 24 time - outs / 3 = 8 time - outs. Then add the number of each kind of time - out to find the total number: 8 time - outs + 24 time - outs + 5 time - outs = 37 time - outs. Then multiply that number by the length of each time - out to find the total time the students spend in time - out: 37 time - outs * 5 minutes / time - out = 185 minutes. The answer is 185.
Q: Maria's monthly salary is $2000. 20% of her salary goes to paying tax, and 5% goes to insurance. Also, a quarter of the money left after the deductions is spent on utility bills. How much money does Maria have after the deductions and utility bills payment?
A: Maria's deduction for tax is 2000 x 20% = $400. Her deduction for insurance is 2000 x 5% = $100. Maria's total deductions is $400 + $100 = $500. After the deductions, Maria has only $2000 - $500 = $1500 left from her salary. Then, Maria pays $1500 / 4 = $375 for the utility bills. So, Maria has $1500 - $375 = $1125 after the deductions and utility bills payment. The answer is 1125.
