Question: At a university there are 1800 students. 30% of all the students are from other countries. Starting next semester, 200 new foreign students will begin studying at this University. How many foreign students will then study at the University if all other students continue to study?
Answer: In the beginning, there are 30 / 100 * 1800 students = 540 foreign students. In the next semester, there are going to be 540 foreign students + 200 foreign students = 740 foreign students in total. The answer is 740.
[Question]Mckenna starts her day at 8:00 a.m. She works in her office up to 11:00 a.m. then joins her team of developers at the conference room to talk about projects up to 13:00, from which she works for another two hours and then heads home. How many hours does Mckenna stay at work?
[Answer]From 8:00 to 11:00, Mckenna spends 11:00 - 8:00 = 3 hours at work. When she joins the developers in the conference room for the meeting, she spends an additional 13:00 - 11:00 = 2 hours at work. So far, she has spent 3 + 2 = 5 hours at work. When she works for an additional 2 hours before heading home, her total work hours become 5 + 2 = 7 hours. The answer is 7.
Q: Frank picked 36 apples. Susan picked 3 times as many apples as Frank. If Susan gave out half of her apples, and Frank sold a third of his, how many in total do they have left?
A: Susan picked 3 times as much as 36 which is 3 * 36 = 108 apples. She gave out half which is 108 * (1 / 2) = 54 apples. She now has 108 - 54 = 54 apples. Frank sold a third of 36 which is 36 * (1 / 3) = 12 apples. Frank now has 36 - 12 = 24 apples. Altogether they now have 54 + 24 = 78 apples. The answer is 78.

[Question]Jenna is on a road trip. She drives for 2 hours at 60mph. She takes a bathroom break, and then she continues driving for 3 hours at 50 mph. She can drive for 30 miles on one gallon of gas. If one gallon of gas costs $2, how much money does she spend on gas for her trip?
[Answer]First she drives 2 hours * 60 mph = 120 miles. Then she drives 3 hours * 50 mph = 150 miles. The total miles driven is 120 + 150 = 270 miles. Jenna uses 270 / 30 = 9 gallons of gas. The cost of gas is 9 * $2 = $18. The answer is 18.
[Question]One pie costs $4 for a piece. Each pie is having 3 pieces. During one hour the bakery can make 12 pies. Creating one pie costs the bakery $0.5. Considering the bakery would be able to sell all pie pieces, how much money would it make?
[Answer]
If the bakery can make 12 pies, this means there would be 12 * 3 = 36 pie pieces. For all the pieces the bakery would make 36 * 4 = $144. The cost of making 12 pies is 12 * 0.5 = $6. That means the bakery would make 144 - 6 = $138. The answer is 138.
