Question: Marta is arranging floral centerpieces for a reception party. Each arrangement needs to have 8 roses,12 daisies, 3 snapdragons and twice as many lilies. The reception will have 10 tables. How many flowers will she need in total to fill this order?
Answer: She needs twice as many lilies as the 3 snapdragons in the arrangement so she needs 2 * 3 = 6 lilies. She needs 8 roses, 12 daisies, 3 snapdragons and 6 lilies for a total of 8 + 12 + 3 + 6 = 29 flowers per arrangement. She needs 29 flowers per each of the 10 tables for a total of 29 * 10 = 290 flowers. The answer is 290.

Question: Before Cameron broke his right arm, he was able to type 10 words per minute on his phone. After he broke his arm, he had to use his left hand for a while, and he could only type 8 words per minute. What is the difference between the number of words he could type in 5 minutes before and after he broke his arm?
Answer: Before Cameron broke his hand he could type 5 × 10 = 50 words in 5 minutes. After he broke his hand he could only type 5 × 8 = 40 words in 5 minutes. The difference between the number of words he could type in 5 minutes before and after he broke his arm is 50 - 40 = 10 words. The answer is 10.

Question: At A.T. Cross Luxury Pens, a pencil sells at twenty-five cents while a pen sells at fifteen cents. Bowen buys 40 pens and 2/5 times more pencils than pens from A.T. Cross Luxury Pens. Calculate the total amount of money Bowen spends.
Answer:
Bowen bought 2 / 5 * 40 pens = 16 more pencils than pens. The total number of pencils that he bought is 40 pencils + 16 pencils = 56 pencils. If each pencil costs twenty - five cents, the total amount of money he spent on pencils is 56 pencils * $0.25 / pencil = $14. On pens, Bowen spent $0.15 / pen * 40 pens = $6. The total amount of money Bowen spent is $14 + $6 = $20. The answer is 20.
