[Question]In the park, the first rose bush has 12 red flowers. The second rose bush has 18 pink flowers. The third rose bush has 20 yellow flowers. The fourth rose bush has 8 orange flowers. For her vase, Lorelei picks 50% of the red roses, 50% pink roses, 25% of the yellow roses, and 25% orange roses. How many roses are in her vase?
[Answer]The number of red roses Lorelei picks is 12 x 50% = 6 roses. The number of pink roses Lorelei picks is 18 x 50% = 9 roses. The number of yellow roses she picks is 20 x 25% = 5 roses. The number of orange roses she picks is 8 x 25% = 2 roses. The total number of roses in her vase is 6 + 9 + 5 + 2 = 22 roses. The answer is 22.

[Question]On Tuesday last week, Leo dropped off 10 pairs of trousers and some shirts at Sudsy Laundry. He was given a bill of $140, charged at $5 per shirt and $9 for each pair of trousers. When he went to pick up his clothes yesterday, the attendant insisted that he had only dropped off 2 shirts. Leo reported the matter to the manager, who ordered the attendant to search for the rest of Leo’s shirts. How many shirts were missing?
[Answer]The cost of laundering all of Leo’s trousers is 10 * 9 = 90 dollars. Since the total bill was 140 dollars, this means that all the shirts were cleaned for 140 - 90 = 50 dollars. As each shirt is cleaned at 5 dollars, Sudsy Laundry therefore laundered a total of 50 / 5 = 10 shirts. The missing shirts are therefore 10 - 2 = 8 shirts. The answer is 8.

[Question]Clara is selling boxes of cookies to raise money for a school trip. There are 3 different types for sale. The first type has 12 cookies per box. The second type has 20 cookies per box, and the third type has 16 cookies per box. If Clara sells 50 boxes of the first type, 80 boxes of the second type, and 70 boxes of the third type, how many cookies does she sell?
[Answer]Clara sells 600 cookies of the first type because 12 * 50 = 600. She sells 1600 cookies of the second type because 20 * 80 = 1600. She sells 1120 cookies of the third type because 16 * 70 = 1120. Thus, Clara sells 3300 cookies total because 600 + 1600 + 1120 = 3320 cookies. The answer is 3320.

Kevin begins the day with 15 phones and repairs 3 by the afternoon, so Kevin still has to repair 15 - 3 = 12 phones. A client drops off 6 additional phones that require fixing, increasing the total to 12 + 6 = 18 phones. If Kevin's coworker helps Kevin fix half of the phones, then each person needs to fix 18 / 2 = 9 phones. The answer is 9.
