Question: A wheel on a certain machine makes 6 turns every 30 seconds. How many turns does it make in two hours?
Answer: Step-by-step reasoning process: Since there are 60 seconds in 1 minute, then there are 60 / 30 = 2 sets of 30 seconds in a minute. So a wheel makes 6 x 2 = 12 turns in 1 minute. Since there are 60 minutes in 1 hour, then a wheel makes 12 x 60 = 720 turns in an hour. Therefore, the wheel makes 720 x 2 = 1440 turns in 2 hours.
So the answer is 1440.

Question: Miley bought two cellphones for her parents. Each cellphone costs $800 but, since she is buying two units, she will receive a 5% discount for the total cost. How much did Miley pay?
Answer: Step-by-step reasoning process: Two cellphones cost $800 x 2 = $1600. The 5% discount amounts to $1600 x 5 / 100 = $80. So Miley paid $1600 - $80 = $1520.
So the answer is 1520.

Question: Lola plays basketball on her school team. Her team scored twice at many points at their last home game than their first away game. At the second away game, they scored eighteen points more than the previous away game. At the third away game, they scored two more points than at their second. If Lola’s team scored 62 points at their last home game, how many points do they have to score in their next game to bring their cumulative points up to four times the score from their last home game?
Answer: Step-by-step reasoning process: At their following away game, Lola’s team scored half as many points as at their home game, so they scored 62 / 2 = 31 points. At the second away game, they scored 31 + 18 = 49 points. At the third away game, they scored 49 + 2 = 51 points. A cumulative score of four times their last home game is 4 * 62 = 248 points. Thus, Lola’s team has to score 248 - 193 = 55 points to bring their cumulative points up to 248.
So the answer is 55.

Question: Scott wants to make and freeze a large batch of ratatouille. At the farmers' market he buys 5 pounds of eggplants and 4 pounds of zucchini at $2.00 a pound. He needs 4 pounds of tomatoes that are $3.50 a pound. The onions are $1.00 a pound and he needs 3 pounds. Then he needs a pound of basil which is sold for $2.50 per half pound. If this yields 4 quarts, how much does each quart cost?
Answer:
Step-by-step reasoning process: He buys 5 pounds of eggplants and 4 pounds of zucchini so he buys 5 + 4 = 9 pounds of produce. These 9 pounds are $2.00 a pound for a total of 9 * 2 = $18.00. He needs 4 pounds of tomatoes that are $3.50 a pound for a total of 4 * 3.50 = $14.00. He needs 3 pounds of onions that are $1.00 a pound so that's 3 * 1 = $3.00. The basil is sold by the half - pound and he needs a full pound so that's 2.50 * 2 = $5.00. The eggplants and zucchinis cost $18.00, the tomatoes are $14.00, the onions are $3.00 and the basil is $5.00 for a total of 18 + 14 + 3 + 5 = $40.00. This recipe makes 4 quarts and the total price of the vegetables was $40.00 so each quart costs 40 / 4 = $10.00.
So the answer is 10.
