Q: John decides to take up illustration. He draws and colors 10 pictures. It takes him 2 hours to draw each picture and 30% less time to color each picture. How long does he spend on all the pictures?
A: The coloring takes 2 * .3 = .6 hours less than the drawing. So it takes 2 - .6 = 1.4 hours per picture. So it takes him 2 + 1.4 = 3.4 hours per picture. That means it takes 3.4 * 10 = 34 hours. The answer is 34.
Question: Eugene built a model house out of toothpicks and a deck of playing cards. For every card, he used 75 toothpicks. The deck of playing cards had 52 cards, and Eugene used all but 16 of the cards to build his house. If a box of toothpicks contains 450 toothpicks, how many boxes of toothpicks did Eugene use to create his model house?
Answer: If Eugene used all but 16 of the 52 cards, then he used 52 - 16 = 36 cards. If for every card he used 75 toothpicks, then a box of toothpicks would have enough toothpicks for 450 / 75 = 6 cards. Since one box has enough toothpicks for 6 cards, then for 36 cards he would need 36 / 6 = 6 boxes of toothpicks. The answer is 6.
[Question]Joanna has $8. Compared to her money, her brother has thrice as much while her sister has only half as much. How much money do the three of them have altogether?
[Answer]Joanna has $8. Joanna's brother has thrice as much as Joanna, so he has $8 * 3 = $24. Her sister has half as much as Joanna, then she has $8 / 2 = $4. Together they have $8 + $24 + $4 = $36 altogether. The answer is 36.
Q: Margo donated $4300 to Jayden's fundraising campaign. If Julie donated $4700 to Jayden's campaign, What's half the difference in the amount they contributed?
A: If Julie donated $4700 to Jayden's campaign, and Margo donated $4300, the difference in their contribution is $4700 - $4300 = $400. Half the difference in the amount they contributed is 1 / 2 * $400 = $200. The answer is 200.
Question: There are 10 cars parked in a mall's parking lot, each with the same number of customers inside. Each customer only makes 1 purchase. If the sports store makes 20 sales and the music store makes 30 sales, how many customers are in each of the cars?
Answer: As each sale represents a customer, there must be a total of 20 sports store sales + 30 music store sales = 50 customers. There is an equal number of customers in every car, so there must be 50 total customers / 10 cars = 5 customers in each car. The answer is 5.
