Q: Stephen ordered 2 large pizzas, both cut into 12 slices. He ate 25% of the pizza. His friend Pete ate 50% of the remaining pizza. How many slices are left over?
A: He ordered 2 pizzas, each cut into 12 slices so that’s 2 * 12 = 24 slices. Stephen ate 25% of the pizza so he ate .25 * 24 = 6 slices. That leaves 24 - 6 = 18 slices. 18 slices are left and Pete eats 50% of 18 slices so he eats 18 * .50 = 9 slices. If there were 18 slices and Pete ate 9 slices then there are 18 - 9 = 9 slices left over. The answer is 9.
Question: A spiral notebook costs $15, and a personal planner costs $10. How much would it cost in total to buy 4 spiral notebooks and 8 personal planners at a 20% discount?
Answer: If a spiral notebook cost $15, a 20% discount would reduce the price by 20 / 100 * 15 = $3. At a 20% discount, the buying price of a spiral notebook book is $15 - $3 = $12. At the same discount, a personal planner cost would reduce by 20 / 100 * $10 = $2. The new buying price of a personal planner will be $10 - $2 = $8. To buy four spiral notebooks at a 20% discount, you'll pay 4 * $12 = $48. At the same time discount, you'll buy eight personal planners at a cost pf 8 * $8 = 64. In total, to buy eight personal planners and four spiral notebooks, you'd have to pay $64 + $48 = $112. The answer is 112.
[Question]Ken had fifty pencils, and he wanted to share some of them with his two friends, Manny and Nilo. Ken gave ten pencils to Manny and ten more pencils to Nilo than he gave to Manny. He kept the rest of the pencils. How many pencils did Ken keep?
[Answer]Nilo received 10 + 10 = 20. Thus, Ken gave a total of 10 + 20 = 30. Therefore, Ken kept 50 - 30 = 20 pencils. The answer is 20.
Q: Jason has a carriage house that he rents out. He’s charging $50.00 per day or $500.00 for 14 days. Eric wants to rent the house for 20 days. How much will it cost him?
A: He wants to rent for 20 days and there is a deal if you rent for 14 days so that leaves 20 - 14 = 6 individual days. Each individual day is $50.00 and he will have 6 individual days for a total of 50 * 6 = $300.00. 14 days costs $500.00 and 6 days costs $300.00 for a total of 500 + 300 = $800.00. The answer is 800.
