[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]Lucca bought 200 pieces of bread. Lucca ate 1/4 of the pieces of bread in one day, and 2/5 of the remaining pieces the next day. If he ate half of the remaining pieces on the third day, calculate how many pieces of bread are remaining.
[Answer]On the first day, Lucca ate 1 / 4 * 200 = 50 pieces. The number of pieces remaining after the first day is 200 - 50 = 150. On the second day, Lucca ate 2 / 5 * 150 = 60 pieces of bread. The pieces of bread that remained after the second day is 150 - 60 = 90. If Lucca ate half of the remaining pieces of bread on the third day, he ate 1 / 2 * 90 = 45 pieces. The pieces of bread that are remaining after the third day are 90 - 45 = 45. The answer is 45.

[Question]Sarah is playing tic-tac-toe. She wins $1 for every game she wins, $0 for every game she ties, and she loses $2 for every game she loses. If she played 100 games where she tied 40 of them, and she lost $30, how many games did she win?
[Answer]
She either won or lost 60 games because 100 - 40 = 60. We know that 1(60 - Losses) - 2(Losses) = - 30 because she lost $30. Therefore 60 - Losses - 2 Losses = - 30. Therefore - 3 Losses = - 90. Therefore, Losses = 30. The answer is 30.
