Q: Taro and Vlad play a video game competition together, earning 5 points for every win. After playing 30 rounds, Taro scored 4 points less than 3/5 of the total points scored. How many total points did Vlad score?
A: If they played 30 rounds, the total possible points from wins are 5 * 30 = 150 points. Scoring 3 / 5 of the total possible points earns you 3 / 5 * 150 points = 90 points. If Taro scored 4 points less than 3 / 5 of the total points, he scored 90 points - 4 points = 86 points. If the total points scored in the game is 150, then Vlad scored 150 points - 86 points = 64 points. The answer is 64.
Question: Mary bought six apples from the store. From the apples she bought, for each that Mary ate, she planted two trees from the remaining ones. How many apples did Mary eat?
Answer: She planted eight trees. This means she used half of that amount of apples, which is 8 trees / 2 trees / apple = 4 apples. That means that she planted four of the six apples she bought, leaving only 6 apples - 4 apples = 2 apples to be eaten. The answer is 2.
[Question]Silvia’s bakery is offering 10% on advanced orders over $50.00. She orders 2 quiches for $15.00 each, 6 croissants at $3.00 each and 6 buttermilk biscuits for $2.00 each. How much will her order be with the discount?
[Answer]She orders 2 quiches for $15.00 each so they cost 2 * 15 = $30.00. She orders 6 croissants at $3.00 each so they cost 6 * 2.5 = $18.00. She orders 6 biscuits at $2.00 each so they cost 6 * 2 = $12.00. Her advance order is 30 + 18 + 12 = $60.00. Her advance order is over $50.00 so she can get 10% off so .10 * 60 = $6.00. Her order is $60.00 and she gets $6.00 off so her advanced order will cost 60 - 6 = $54.00. The answer is 54.
Q: Bobby needs to buy a new pair of fancy shoes. He decides to go to a cobbler and get them handmade. The cobbler charges $250 to make the mold. He then charges $75 an hour for 8 hours to make the shoes. The cobbler agrees to only charge 80% of the cost for work to make the shoes, since it is his first pair of shoes. How much did Bobby pay?
A: The cost of labor is 75 * 8 = $600. So Bobby pays 600 * .8 = $480. So that means Bobby pays 480 + 250 = $730. The answer is 730.

Q: An iron bar measures 12 cm by 8 cm by 6 cm. A factory wants to melt ten iron bars and mold them into iron balls. Each iron ball has a volume of 8 cubic cm. How many iron balls have been molded?
A:
The volume of 1 iron bar is 12 cm x 8 cm x 6 cm = 576 cubic cm. The volume of 10 iron bars is 10 x 576 cubic cm = 5760 cubic cm. Therefore, there are 5760 / 8 = 720 iron balls that have been molded. The answer is 720.
