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: Carmela has $7 and each of her four cousins has $2. How much will Carmela have to give to each of her cousins so that she and her cousins will have the same amount of money?
Answer: Carmela's four cousins have a total of $2 x 4 = $8. The total money they all have is $7 + $8 = $15. There will be 1 (Carmela) + 4 (cousins) = 5 people who will be sharing equally the money. So each of them should get $15 / 5 = $3. Hence, Carmela has to give a total of $7 - $3 = $4 to her 4 cousins. Therefore, each of her cousins will get $4 / 4 = $1. The answer is 1.

Q: Shelby was having a movie party for her birthday. She and her mom made a dozen bags of buttered popcorn and 10 bags of caramel popcorn. Her brother Alan took 3 bags of buttered popcorn and 1 bag of caramel popcorn for his friends. How many bags of popcorn does Shelby have left for the party?
A: Shelby and her mom made 12 bags of buttered popcorn + 10 bags of caramel popcorn = 22 bags. Of those 22 bags, her brother took 3 bags of buttered popcorn + 1 bag of caramel popcorn = 4 bags. So now Shelby has 22 bags 4 bags = 18 bags of popcorn left. The answer is 18.
Question: Mark is buying asphalt to pave a new section of road. The road will be 2000 feet long and 20 feet wide. Each truckload of asphalt will cover 800 square feet of road. If each truckload costs $75, and there's a 20% sales tax, how much will Mark need to pay for asphalt?
Answer: First, calculate how many square feet of road Mark needs to cover by multiplying the length by the width: 2000 feet * 20 feet = 40,000 sq ft. Then divide the square footage of road by the number of square feet each truckload will cover: 40,000 sq ft / 800 sq ft / truckload = 50 truckloads. Now multiply the number of truckloads by the cost per truckload: $75 / truckload * 50 truckloads = $3750. Now calculate the sales tax by multiplying $3750 by 20%: $3750 * .2 = $750. Now add the sales tax to the cost of the asphalt to find the total: $750 + $3750 = $4500. The answer is 4500.
Q: A woman is trying to decide whether it will be quicker to take an airplane or drive herself to a job interview. If she drives herself, the trip will take her 3 hours and 15 minutes. If she takes an airplane, she will first need to drive 10 minutes to the airport, and then wait 20 minutes to board the plane. After that, she will be on the airplane for one-third of the time it would have taken her to drive herself before landing in the destination city. Finally, it will take her an additional 10 minutes to get off the airplane and arrive at her interview site after the plane lands. Given this information, how many minutes faster is it for her to take the airplane?
A:
First, we must convert the driving time of 3 hours and 15 minutes to minutes. Since there are 60 minutes in an hour, driving takes a total of 3 * 60 + 15 = 195 minutes. Next, the woman will be on the airplane for one - third of 195 minutes, or 195 / 3 = 65 minutes. Therefore, in total, the airplane trip will take the woman 10 + 20 + 65 + 10 = 105 minutes. Thus, the airplane trip is 195 - 105 = 90 minutes faster than driving herself to the interview. The answer is 90.
