[Question]: A garden is filled with 105 flowers of various colors. There are twice as many red flowers as orange. There are five fewer yellow flowers than red. If there are 10 orange flowers, how many pink and purple flowers are there if they have the same amount and there are no other colors?
[Answer]: The number of red flowers is twice as many as orange so 2 * 10 orange = 20 red flowers. The number of yellow flowers is 5 less than red so 20 red - 5 = 15 yellow flowers. The number of red, orange and yellow flowers is 20 red + 10 orange + 15 yellow = 45 flowers. The number of pink and purple flowers total is 105 flowers total - 45 flowers that are not pink or purple = 60 flowers. The number of pink and purple flowers each is 60 flowers / 2 = 30 flowers each.
So the answer is 30.

[Question]: Matthew, the baker, arrives at work early every morning to make his famous caramel-apple coffee cakes for the day. It usually takes Matthew 1 hour to assemble ingredients, 1.5 hours to bake the cakes, and another 1 hour to decorate each cake with cinnamon sprinkles. One day, Matthew's oven failed to reach the correct temperature and it took twice as long for the cakes to bake as they usually take. On that day, how long did it take, in hours, for Matthew to make his famous caramel-apple coffee cakes?
[Answer]: Twice 1.5 hours is 2 * 1.5 = 3 hours. Thus, on that day, it took Matthew 1 + 3 + 1 = 5 hours to make the cakes.
So the answer is 5.

[Question]: Mark spent 220 dollars to fix his car. It needed two parts that cost 20 dollars each, and labor cost .5 dollars a minute. How many hours did the mechanic work?
[Answer]:
Labor cost is .5 * 60 = 30 dollars per hour. The cost for parts is 20 * 2 = $40. The total cost for labor is 220 - 40 = $180. He spent 180 / 30 = 6 hours on labor.
So the answer is 6.
