On Sunday Alice bought 4 pints of strawberry ice cream. The next day she went back and bought three times that number of pints. On Tuesday she bought one-third of the number of pints she bought the day before. On Wednesday she returned half of the pints she bought the day before because they were expired. How many pints of ice cream did she have on Wednesday? Give the rationale and then the answer.
Let's think step by step. On Monday she bought 4 * 3 = 12 pints. On Tuesday she bought 12 / 3 = 4 pints. Before she returned any she had 4 + 12 + 4 = 20 pints. She returned 4 / 2 = 2 pints. After returning she had 20 - 2 = 18 pints.. The answer is: 18.

A plane flies between 4 cities; A, B, C and D. Passengers board and alight at each airport in every city when it departs and lands, respectively. The distance between city A and city B is 100 miles. The distance between city B and city C is 50 miles more than the distance between city A and city B. The distance between city C and city D is twice the distance between city B and city C. Calculate the total distance between city A and city D. Give the rationale and then the answer.
Let's think step by step. Since the distance between city A and B is 100 miles, and city B and C are 50 more miles apart than city A and B, then city B and C are 100 + 50 = 150 miles apart. The plane's total flying distance between cities A and C is 100 + 150 = 250 miles. The distance between city C and city D is twice the distance between city B and city C, meaning city C and city D are 2 * 150 = 300 miles apart. The plane flies a distance of 250 + 300 = 550 miles from city A to city D.. The answer is: 550.

Kylie makes 10 beaded necklaces on Monday and 2 beaded necklaces on Tuesday. Then Kylie makes 5 beaded bracelets and 7 beaded earrings on Wednesday. 20 beads are needed to make one beaded necklace. 10 beads are needed to make one beaded bracelet. 5 beads are needed to make one beaded earring. How many beads does Kylie use in total to make her jewelry? Give the rationale and then the answer.
Let's think step by step. Kylie makes 10 + 2 = 12 beaded necklaces. The number of beads used for the necklaces is 12 * 20 = 240 beads. The number of beads used for the bracelets is 5 * 10 = 50 beads. The number of beads used for the earrings is 7 * 5 = 35 beads. The total number of beads used is 240 + 50 + 35 = 325 beads.. The answer is: 325.
