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]This year the Oscar swag bags include two diamond earrings that cost $6,000 each, a new iPhone that costs $2,000, and some designer scarves that each cost $1,500. If the total value of the swag bag is $20,000, how many scarves are there?
[Answer]First find the total cost of the diamond earrings: $6,000 / earring * 2 earrings = $12,000. Then subtract the cost of the earrings and iPhone from the total cost of the bags to find the cost of all the scarves: $20,000 - $12,000 - $2,000 = $6,000. Then divide the total cost of the scarves by the cost per scarf to find the number of scarves: $6,000 / $1,500 / scarf = 4 scarves. The answer is 4.
Q: Every week of last month Paul tried out a new cake recipe. The first week, he followed a cake recipe that called for 24 cups of sugar. Each week after that, he reduced the amount of sugar by half. How much sugar did he use for the cake on the fourth week?
A: On the 2nd week, Paul halved the first week's sugar, therefore he used 24 / 2 = 12 cups. The third week, Paul used 12 / 2 = 6 cups. The fourth week, he used 6 / 2 = 3 cups. The answer is 3.
Question: There are 200 snakes in a park. There are three times as many pythons as boa constrictors. If there 40 boa constrictors and the rest of the snakes are rattlesnakes, calculate the total number of rattlesnakes in the park.
Answer: If the number of pythons is three times the number of boa constrictors, then there are 3 * 40 = 120 pythons. Together, the number of pythons and boa constrictors is 120 + 40 = 160. If there are 200 snakes in the park, the number of rattlesnakes is 200 - 160 = 40. The answer is 40.
[Question]A jar on the family's counter contains change they've been saving a trip to the ice cream shop. There are 123 pennies, 85 nickels, 35 dimes, and a number of quarters. All five family members get a double scoop, which costs $3 each. After the trip, they have 48 cents left over. How many quarters were in the jar?
[Answer]The family spent $15 on ice cream because 5 x 3 = 15. They total amount of change they had was $15.48 because 15 + .48 = 15.48. They have $1.23 in pennies because 123 x .01 = 1.23. They have $4.25 in nickels because 85 x .05 = 4.25. They have $3.50 in dimes because 35 x .1 = 3.5. Without the quarters they have a total of $8.98 because 1.23 + 4.25 + 3.5 = 8.98. They have $6.5 worth of quarters because 15.48 - 8.98 = 6.5. They have 26 quarters because 6.5 / .25 = 26. The answer is 26.
