Q: Dexter went to the mall and saw that Apple products are on sale. He wants to buy an iPhone 12 with a 15% discount and an iWatch with a 10% discount. The price tag shows that an iPhone 12 costs $800 while an iWatch costs $300. Upon check out, he will receive a further 2% cashback discount. How much would the items cost in total after the discount and cashback?
A: 931
Step-by-step reasoning process: The discount for an iPhone 12 is $800 x 15 / 100 = $120. So, the iPhone will now cost $800 - $120 = $680. The discount for an iWatch is $300 x 10 / 100 = $30. So, the iWatch will now cost $300 - $30 = $270. The total cost of the iPhone and iWatch is $680 + $270 = $950. The cashback will be $950 x 2 / 100 = $19. Thus, Dexter will only pay $950 - $19 = $931.

Q: A local business was selling 25 raffle tickets to raise money for charity. Each ticket cost $2.00 apiece. They sold all the tickets and also received 2 $15 donations and a $20 donation. How much money did they raise?
A: 100
Step-by-step reasoning process: They sold 25 raffle tickets at $2.00 a piece so 25 * 2 = $50.00. They received 2 $15.00 donations so 2 * 15 = $30. With another donation of $20, in total, they raised 50 + 30 + 20 = $100.00.

Q: Johan has a ten-bedroom house with 8 walls in each room. He paints 3/5 of the rooms in the house green and paints the rest of the rooms with purple color. How many walls in the house did he paint purple?
A: 32
Step-by-step reasoning process: Since Cristian's house has ten rooms, he painted 3 / 5 * 10 = 6 rooms with green color. The number of rooms he painted with purple is 10 - 6 = 4 rooms. Since each room in the house has eight walls, the number of walls painted purple is 8 * 4 = 32.
