Q: 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?
A: 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]A yearly book sale is held in school where students can sell their old books at a cheaper price. Two-fifths of Lovely's books can be sold for $2.50 each and the rest for $2 each. How much will Lovely earn if all 10 books were sold?
[Answer]Lovely will sell 10 x 2 / 5 = 4 books for $2.50 each. She will sell 10 - 4 = 6 books for $2 each. Her earnings for the 4 books at $2.50 will be $2.50 x 4 = $10. Her earnings for the 6 books for $2 each will be $2 x 6 = $12. Thus, Lovely's total earning if all 10 books are sold is $10 + $12 = $22. The answer is 22.

Question: John buys a chair. He then buys a table that is 3 times the price of the chair. Then, he buys a couch that is 5 times the price of the table. If John paid $380 for all these items, what is the price of the couch?
Answer: Let x be the price of the chair. The table costs 3 * x. The couch costs 3 * x * 5 = 15 * x. x + 3 * x + 15 * x = 380. 19 * x = 380. x = 20. The couch costs 20 * 15 = 300 dollars. The answer is 300.
Q: A small, old, wooden bridge can hold up to 100 kilograms at once. Mike, Megan, and Kelly are three children who decided to cross the bridge at the same time. Kelly weighs 34 kilograms, which is 15% less than Megan. Mike weighs 5 kilograms more than Megan. How much too much do the three children weigh together to cross the bridge?
A:
If Kelly weighs 15% less than Megan, this means Kelly's weight is 100 - 15 = 85% of Megan's weight. 85% is 0.85, so Megan weighs 34 / 0.85 = 40 kilograms. Mike weighs 5 kilograms more than Megan, so he weighs 40 + 5 = 45 kilograms. In total all three kids weigh 34 + 40 + 45 = 119 kilograms. That means to cross the bridge safely, they weigh 119 - 100 = 19 kilograms too much. The answer is 19.
