Question: Miriam spent 30 minutes doing laundry, 15 minutes cleaning the bathroom, a certain amount of time cleaning her room, and 40 minutes doing homework. If she spent a total of two hours on these tasks, how long, in minutes, did she spend cleaning her room?
Answer: There are 30 + 15 + 40 = 85 minutes accounted for. She spent 2 * 60 = 120 minutes. She spent 120 - 85 = 35 minutes cleaning her room. The answer is 35.
[Question]A forester is planting trees. The forest already has 30 native trees. On Monday he triples the number of total trees in the forest by planting new trees. On Tuesday, he plants a third of the amount he planted on Monday. How many trees has the forester planted in total?
[Answer]Let M be the number of trees he plants on Monday. On Monday the forest was three times larger from the trees that were originally there and the M trees: 3 * 30 = 30 + M trees. So, 90 = 30 + M. And, M = 60 trees. On Tuesday, he planted 60 trees / 3 = 20 trees. In total, he has planted 60 trees + 20 trees = 80 trees. The answer is 80.
Q: Andrew installed hardwood flooring in his house. His bedroom took eight wooden planks, his living room took twenty planks, and his kitchen took eleven planks. The guest bedroom took two fewer planks than Andrew’s bedroom, and each of his two hallways took four planks. He accidentally ruined three planks in each bedroom by dragging furniture over them and had to replace them. He ended up with six leftover planks at the end. How many wooden planks did Andrew buy to start with?
A: Andrew’s guest bedroom took 8 - 2 = 6 wooden planks. His hallways took 2 * 4 = 8 planks. In two bedrooms, he ruined 3 planks each, so the bedrooms took an extra 3 * 2 = 6 planks. In all, he used 8 + 20 + 11 + 6 + 8 + 6 = 59 planks for his whole house. Andrew had 6 leftover planks, so he bought 59 + 6 = 65 wooden planks to start with. The answer is 65.
Question: I bought a TV for $1700 excluding tax. What is the price of the television when calculating 15% of the value-added tax?

[Question]Mark's basketball team scores 25 2 pointers, 8 3 pointers and 10 free throws. Their opponents score double the 2 pointers but half the 3 pointers and free throws. What's the total number of points scored by both teams added together?
[Answer]Mark's team scores 25 2 pointers, meaning they scored 25 * 2 = 50 points in 2 pointers. His team also scores 6 3 pointers, meaning they scored 8 * 3 = 24 points in 3 pointers. They scored 10 free throws, and free throws count as one point so they scored 10 * 1 = 10 points in free throws. All together his team scored 50 + 24 + 10 = 84 points. Mark's opponents scored double his team's number of 2 pointers, meaning they scored 50 * 2 = 100 points in 2 pointers. His opponents scored half his team's number of 3 pointers, meaning they scored 24 / 2 = 12 points in 3 pointers. They also scored half Mark's team's points in free throws, meaning they scored 10 / 2 = 5 points in free throws. All together Mark's opponents scored 100 + 12 + 5 = 117 points. The total score for the game is both team's scores added together, so it is 84 + 117 = 201 points. The answer is 201.
[Question]Mac loves the shape of quarters and is willing to trade money for them, even if he loses value. He tells his brother that he will trade him 3 dimes for a quarter or 7 nickels. He trades for 20 quarters with dimes and 20 quarters with nickels. How many dollars did Mac lose?
[Answer]
Three dimes is equal to $.3 because 3 x .1 = .3. Seven nickels is equal to $.35 because 7 x .05 = .35. Each time he trades with dimes he lose $.05 because .3 - .25 = .05. Each time he traded with nickels he lost $.1 because .35 - .25 = .1. He lost $1 from trading with dimes because 20 x .05 = 1. He lost $2 from trading with nickels because 20 x .1 = 2. He lost $3 total because 1 + 2 = 3. The answer is 3.
