Q: Sean designs and sells patches. He orders his patches in a unit of 100 and is charged $1.25 per patch. If he turns around and sells all 100 patches for $12.00 each, what is his net profit?
A: He orders 100 patches and they cost $1.25 each so the patches are 100 * 1.25 = $125.00. He sells each of the 100 patches for $12.00 each so he makes 100 * 12 = $1,200.00. He makes $1,200.00 selling patches and spends $125.00 to have them made so his net profit is 1200 - 125 = $1,075.00. The answer is 1075.
Question: A milk teas shop was able to sell a total of 50 cups of milk tea yesterday. Two-fifths of their sales are winter melon flavor, three-tenths are Okinawa flavor, and the rest are chocolate flavor. How many cups of chocolate-flavored milk tea were they able to sell yesterday?
Answer: A milk tea shop sold 50 x 2 / 5 = 20 cups of winter melon - flavored milk tea. They sold 50 x 3 / 10 = 15 cups of Okinawa - flavored milk tea. So they sold a total of 20 + 15 = 35 cups of winter melon and Okinawa flavors milk tea. Therefore, they sold 50 - 35 = 15 cups of chocolate - flavored milk tea. The answer is 15.
[Question]Hani said she would do 3 more situps per minute than Diana would. Diana then did 40 situps at a rate of 4 situps per minute. Calculate the total number of situps they did together.
[Answer]Since Diana did 40 situps at a rate of 4 situps / minute, she did situps for 40 / 4 = 10 minutes. Hani had to do 3 + 4 = 7 situps per minute if Diana did 4 situps per minute. So over the 10 minutes Hani did 7 * 10 = 70 situps. Together, the total number of situps they did is 70 + 40 = 110. The answer is 110.
Q: Gunther needs to clean his apartment. It takes him 45 minutes to vacuum the carpets, 60 minutes to dust the furniture, 30 minutes to mop the floors in his kitchen, and 5 minutes to brush each cat, and he has three cats. If he has 3 hours of free time available, and he uses this time to clean his apartment, how many minutes of free time will he have left after he cleans the apartment?
A: It will take 3 * 5 = 15 minutes to brush his cats. All together, it will take 45 + 60 + 30 + 15 = 150 minutes to clean his apartment. In three hours, there are 60 * 3 = 180 minutes. Thus, he will have 180 - 150 = 30 minutes of free time remaining. The answer is 30.
Question: Josephine receives a bill from the hospital for 5000$. 50 percent of the bill is for medication. 25 percent of the remaining bill is for overnight stays, and 175$ is for food. The rest of the bill is for the ambulance ride. How much did the ambulance ride cost?
Answer: Medication:5000(.50) = 2500. Overnight Stays:2500(.25) = 625. 2500 - 625 = 1875. Food:1875 - 175 = 1700$. Ambulance ride:1700$. The answer is 1700.
