Question: Piazzanos Pizzeria has a buy-1-get-1-free special on triple cheese pizzas, and a buy-2-get-1-free special on meat lovers pizzas. If the standard price for a pizza is $5, how much does it cost, in dollars, to purchase 10 triple cheese and 9 meat lovers pizzas using the special pricing?
Answer: Using buy - 1 - get - 1 - free pricing, it costs 1 * $5 = $5 to buy 2 triple cheese pizzas. At $5 per 2 pizzas, it costs $5 / 2 = $2.5 per triple cheese pizza. Using buy - 2 - get - 1 - free pricing, it costs 2 * $5 = $10 to buy 3 meat lovers pizzas. At $10 per three pizzas, it cost $10 / 3 = $3 and $1 / 3 per meat lovers pizza. With the buy - 1 - get - 1 - free pricing, 10 triple cheese pizzas are 10 * $2.5 = $25. With the buy - 2 - get - 1 - free pricing, 9 meat lovers pizzas are 9 * ($3 + $1 / 3) = $30. In total, for 10 triple cheese and 9 meat lovers pizzas, it will cost $25 + $30 = $55. The answer is 55.
[Question]Jordan's dog, Max, was born on the same day that Luka turned 4 years old. Luka is exactly 2 years older than is Aubrey. On Aubrey's 8th birthday, how many years old was Jordan's dog, Max?
[Answer]If Luka is exactly 2 years older than is Aubrey, then on Aubrey's 8th birthday, Luka was 8 + 2 = 10 years old. If Jordan's dog, Max, was born on the same day that Luka turned 4 years old, then when Luka was 10 years old, Max was 10 - 4 = 6 years old. The answer is 6.
Q: A tomato plant has 100 tomatoes. Jane picks 1/4 of that number for use in their house. After a week, she goes back and picks 20 more tomatoes, and the following week picks twice that number. What's the total number of fruits remaining on the tomato plant?
A: When she picks 1 / 4 of the number of tomatoes, she goes home with 1 / 4 * 100 = 25 tomatoes. The total number of tomatoes remaining will be 100 - 25 = 75 tomatoes. After picking 20 more tomatoes the following week, the number of tomatoes remaining is 75 - 20 = 55 tomatoes. The next week she picks twice the number she picked the previous week, that is 20 * 2 = 40 tomatoes. The total number of tomatoes remaining after the final picking is 55 - 40 = 15 tomatoes. The answer is 15.
