[Question]Alice made 52 friendship bracelets over spring break to sell at school. It only cost her $3.00 in materials to make these bracelets. During the break, she gave 8 of her bracelets away. Back at school, she sells all of the remaining bracelets at $0.25 each. How much profit did she make (money earned after paying initial costs) on the sale of her bracelets?
[Answer]She made 52 bracelets but gave 8 away so she had 50 - 8 = 44 bracelets left. She sold 44 bracelets at $0.25 each for a total of 44 * .25 = $11.00. She made $11.00 but she spent $3.00 on the supplies. So her profit would be 11 - 3 = $8.00. The answer is 8.

Question: A football club has a balance of $100 million. The club then sells 2 of its players at $10 million each, and buys 4 more at $15 million each. How much money is left in the club register in millions of dollars?
Answer: The 2 players are sold for a total of 2 * 10 = $20 million. So the club has 100 + 20 = $120 million. The cost of buying 4 more players at $15 million each is 4 * 15 = $60 million. So the club now has 120 – 60 = $60 million. The answer is 60.
[Question]In Mr. Bolton's class of 25 students, 2/5 of the students like maths, 1/3 of the remaining students like science, and the rest of the students like history. Calculate the combined total number of students who like history and those who like maths.
[Answer]If there are 25 students in the class, then 2 / 5 * 25 = 10 students like maths. The number of students who don't like math is 25 - 10 = 15 students. If 1 / 3 of the students that don't like math like science, then 1 / 3 * 15 = 5 students like science. The remaining number of students who enjoy history is 15 - 5 = 10. The combined total for the students who want history and maths is 10 + 10 = 20. The answer is 20.
Q: Jebb buys $50 worth of food at a restaurant with a service fee of 12%. After paying, he gives a $5 tip. How much money did he spend at the restaurant?
A: Jebb paid $50 x 12 / 100 = $6 for service fee. He paid $50 + $6 = $56 for the food and the service fee. The total cost of everything is $56 + $5 = $61. The answer is 61.
Question: Out of the 120 people who attended the party, 1/3 are men while half are women. The rest are children. How many children attended the party?
Answer:
There were 120 / 3 = 40 men at the party. There were 120 / 2 = 60 women at the party. So, there were 40 + 60 = 100 men and women at the party. Thus, 120 - 100 = 20 were children. The answer is 20.
