[Question]Four people in a law firm are planning a party. Mary will buy a platter of pasta for $20 and a loaf of bread for $2. Elle and Andrea will split the cost for buying 4 cans of soda which cost $1.50 each, and chicken wings for $10. Joe will buy a cake that costs $5. How much more will Mary spend than the rest of the firm put together?
[Answer]Mary will spend $20 + $2 = $22. Elle and Andrea will spend $1.5 x 4 = $6 for the soda. Elle and Andrea will spend $6 + $10 = $16 for the soda and chicken wings. Elle, Andrea, and Joe together will spend $16 + $5 = $21. So, Mary will spend $22 - $21 = $1 more than all of them combined. The answer is 1.
Q: In San Diego Zoo, the lion consumes 25 kilograms of meat, and the tiger consumes 20 kilograms of meat per day. If they have 90 kilograms of meat, how many days will the meats last?
A: The lion and tiger's daily consumption of meat is 25 + 20 = 45 kilograms. Therefore, their supply of meat will last for 90 / 45 = 2 days. The answer is 2.
Question: A tank contains 6000 liters of water, 2000 liters evaporated, and then 3500 liters were drained by Bob. How many liters are in the tank if it now rains for 30 minutes and every 10 minutes 350 liters of rain are added to the tank?
Answer: After the first evaporation, the water tank has 6000 liters - 2000 liters = 4000 liters. After the second extraction, the water tank has 4000 liters - 3500 liters = 500 liters. The tank is refilled with rain 30 minutes / 10 minutes = 3 times. The amount of water refilled with rain is 3 times * 350 liters per time = 1050 liters. With the additional rainwater, the water tank has 500 liters + 1050 liters = 1550 liters. The answer is 1550.
[Question]Donna is catering for a party. She makes 20 sandwiches and then cuts them in half, before cutting them in half again. She then gives everyone 8 portions. How many people can she feed?
[Answer]First, we need to determine the overall number of portions. To do this, we begin by performing 20 * 2 = 40 portions after the first halving. Next, we take this portion number and double it again, performing 40 * 2 = 80 portions after the second halving. Lastly, we divide this portion number by the number of portions each person will be served, performing 80 / 8 = 10 people served. The answer is 10.
Q: A store is comparing their profits throughout the year. They had profits of $1,500 in the first quarter of the year, $3,000 in the third quarter, and $2,000 in the fourth quarter. If their annual profits are $8,000, how much profit, in dollars, did they make in the second quarter?
A: In the three quarters we have figures for, the store made a total of $1500 + $3000 + $2000 = $6,500. Subtracting this from their annual profit shows that they made $8000 – $6500 = $1,500 profit in the second quarter. The answer is 1500.
Question: John attends a protest for 4 days. He then attends a second protest for 25% longer than the first. How many days did he spend protesting?
Answer:
The second protest was 4 * .25 = 1 day longer than the first. So the second protest was 4 + 1 = 5 days. Thus he spent 4 + 5 = 9 days protesting. The answer is 9.
