Q: Simon wanted to buy flowers that his mom could plant for Mother's Day. The garden center was offering 10% off all purchases. He bought 5 pansies at $2.50 each, one hydrangea that cost $12.50 and 5 petunias that cost $1.00 each. If he paid with a $50 bill, how much change would Simon receive back from his purchase?
A: 5 pansies at $2.50 each is 5 * 2.50 = $12.50. 5 petunias at $1.00 each 5 * 1 = $5.00. All total he spends 12.50 + 12.50 + 5.00 = $30.00. The sale is 10% off so 30 * .10 = $3.00. The purchase total now comes to 30 - 3 = $27.00. He pays with a $50 bill so 50 - 27 = $23.00. The answer is 23.
Question: Martha collected 90 cans while Diego collected 10 more than half the cans collected by Martha. If both of them should collect a total of 150 cans for their project, how many more cans do they need to collect?
Answer: Half the cans collected by Martha is 90 / 2 = 45. So, Diego collected 45 + 10 = 55 cans. Martha and Diego collected 90 + 55 = 145 cans together. Thus, they need to collect 150 - 145 = 5 more cans. The answer is 5.

Question: Prejean's speed in a race was three-quarters that of Rickey. If they both took a total of 70 minutes to run the race, calculate the total number of minutes that Rickey took to finish the race.
Answer: Let's say Rickey took t minutes to finish the race. If Prejean's speed in the race was three - quarters that of Rickey, and Rickey took t minutes to finish the race, the time that Prejean took to finish the race is 3 / 4 * t = 3 / 4t. Together, Rickey and Prejean took t + 3 / 4t = 70. They took 1 3 / 4 t hours = 70 to finish the race. This is 7 / 4t = 70. t = 70 * 4 / 7. The time that Rickey took to finish the race is t = 40 minutes. The answer is 40.
Q: John is holding a poker night with his friends and is getting the decks of cards ready before his friends show up. After losing so many cards from various decks, John thinks he needs to count exactly how many cards he has to make sure he has enough full decks for the night. Each deck of cards should hold 52 cards. He finds 3 half-full decks of cards and 3 full decks of cards. As he is arranging them, he realizes that the quality of a lot of the cards is quite poor and decides to throw 34 of the cards in the trash. How many cards does John now have?
A:
In the full decks, John has a total of 52 cards in a full deck of cards * 3 full decks of cards = 156 cards. A half - full deck of cards contains 52 cards in a full deck of cards / 2 = 26 cards. So from the half - full decks, John has a total of 26 cards * 3 half - full decks = 78 cards. This is a total of 156 cards from full decks + 78 cards from half - full decks = 234 cards. After throwing some in the trash, he now holds a total of 234 cards - 34 trashed cards = 200 cards. The answer is 200.
