A rope has a length of 200 meters. Stefan cuts the rope into four equal parts, gives his mother half of the cut pieces, and subdivides the remaining pieces into two more equal parts. What's the length of each piece? Give the rationale and then the answer.
Let's think step by step. When Stefan cuts the rope into four equal parts, he gets 200 / 4 = 50 meters of each piece. If he decides to subdivide each piece, he and up with 50 / 2 = 25 meters.. The answer is: 25.

Jean needs to buy 10 new pairs of pants. A store is running a sale for 20% off. If the pants normally retail for $45 each how much will she need to pay for all of them after paying a 10% tax? Give the rationale and then the answer.
Let's think step by step. The discount is 45 * .2 = $9 off each pair. So she pays 45 - 9 = $36 each. So it will cost 36 * 10 = $360 before tax. The tax will add 360 * .1 = $36. So she has to pay 360 + 36 = $396.. The answer is: 396.

Among the career home run leaders for MLB, Hank Aaron has 175 fewer than twice the number that Dave Winfield has. Hank Aaron hit 755 home runs. How many home runs did Dave Winfield hit in his career? Give the rationale and then the answer.
Let's think step by step. Let x be the number of home runs Dave Winfield hit. 755 = 2x - 175. 930 = 2x. x = 465 home runs.. The answer is: 465.
