Q: Joan is answering English and Math exams with 30 and 15 questions, respectively. The English exam is to be completed in 1 hour and the Math exam in 1.5 hours. If Joan wants to spend an equal amount of time on each question, how many more minutes does she have in answering each question on the Math exam than the English exam?
A: Joan is given 1 x 60 = 60 minutes to answer the English exam. So Joan will spend 60 / 30 = 2 minutes for each English question. She is given 1.5 x 60 = 90 minutes to answer the Math exam. So, she will spend 90 / 15 = 6 minutes for each Math question. Hence, Joan has 6 - 2 = 4 minutes more for answering each question in Math than in English. The answer is 4.
Question: Every year, four clowns and thirty children go on a carousel. This year, the candy seller, at the carousel, had 700 candies. The candy seller then sold 20 candies, to each of the clowns and the children, who attended. How many candies did he have left?
Answer: Since there are four clowns at the carousel this year, the candy seller sold 20 * 4 = 80 candies to all the clowns. The thirty children also bought 20 * 30 = 600 candies in total. Altogether, the candy seller sold 600 + 80 = 680 candies to the clowns and children at the carousel. The number of candies the candy seller has left is 700 - 680 = 20. The answer is 20.
[Question]Leila went to the supermarket to get some groceries. Then she headed to her mechanic to get her automobile fixed. If fixing her automobile cost $350 which was $50 more than thrice the amount she spent at the supermarket, how much has she spent altogether?
[Answer]Reversing the steps to obtain the amount she spent at the supermarket, $50 less than $350 is $350 - $50 = $300. If $300 was thrice the amount she spent at the supermarket, then the amount spent at the supermarket was $300 / 3 = $100. In addition to what she spent fixing her auto, she spent $100 + $350 = $450 altogether. The answer is 450.
Q: Tina buys a loaf of bread for $50, 2oz of ham for $150, and a cake for $200. What percent of the cost is the ham and bread?
A: The total cost of buying bread and ham was $50 + $150 = $200. Together with the cake, Tina paid $200 + $200 = $400 for the items. Since the total percentage for all the items is 100%, the cost of ham and bread is $200 / $400 * 100% = 50% of the total cost of items. The answer is 50.
Question: To run his grocery store, Mr. Haj needs $4000 a day. This money is used to pay for orders done, delivery costs and employees' salaries. If he spends 2/5 of the total operation costs on employees' salary and 1/4 of the remaining amount on delivery costs, how much money does he pay for the orders done?
Answer: The total amount of money Mr. Haj used to pay for employee salary is 2 / 5 * $4000 = $1600. After paying the employee salaries, Mr. Haj remains with $4000 - $1600 = $2400. He also uses 1 / 4 * $2400 = $600 on delivery costs. The remaining amount of money that he uses to pay for orders is $2400 - $600 = $1800. The answer is 1800.
Q: At Mario's barbershop haircuts are 50% more expensive during the weekends. If Mario paid $18 for his last haircut on Monday, how much he would have paid the day before?
A:
Mario's $18 cut on Monday would have been 50% more expensive on Sunday or $18 * 50% = $9 more expensive. That means he would have paid $9 more on Sunday than what he paid ($18) on Monday or $9 + $18 = $27. The answer is 27.
