Q: A mad scientist created a shrink ray device that, when used on anything, would cause it to shrink by 50%. The scientist, eager to use his new invention, looked through his house for something to shrink zap. The first thing he found and zapped was his wife, who at the time was carrying a tray containing 5 cups filled with coffee. If each coffee cup held 8 ounces of fluid before being zapped, how many ounces of coffee remained after his wife and the cups filled with coffee were shrink zapped?
A: Before the zap, the wife held 5 cups, each with 8 ounces of coffee, for a total of 5 * 8 = 40 ounces of coffee. After the zap, the coffee cups and their contents were shrunk by 50%, for a total of 0.5 * 40 = 20 ounces of coffee. The answer is 20.
Question: If Billy sleeps 6 hours one night, then 2 more hours than that the following night, and then half the previous amount the following night, and then finally triple the previous amount the final night, how much did he sleep in that four day period?
Answer: Billy slept 6 hours the first night. He then slept 6 + 2 = 8 hours the second night. Billy then slept 8 / 2 = 4 hours the third night. Finally, Billy slept 4 * 3 = 12 hours the fourth night. In total, Billy slept 6 + 8 + 4 + 12 = 30 hours. The answer is 30.
[Question]The trip from Philip's house to the children's school is 2.5 miles, and the trip to the market is 2 miles. He makes the round trip to school two times (when taking the children to school and when bringing them back) every day for 4 days a week. Then he makes a round trip to the market once during weekends. What is his car's mileage for a typical week?
[Answer]Making the round trip to school means driving from the house to school and then back, for a total of 2.5 + 2.5 = 5 miles. He makes this trip twice in one day for a total of 2 * 5 = 10 miles. He does this 4 times in a week for a total of 4 * 10 = 40 miles. The round trip (once a week) to the market is 2 + 2 = 4 miles. His total mileage for a typical week = 40 + 4 = 44 miles. The answer is 44.
Q: Cherry put up a delivery service. She charges $2.50 for a 3-5 kilograms cargo and $4 for a 6-8 kilograms cargo. If she delivers four 5 kilograms cargo and two 8 kilograms cargo per day, how much money will she earn in a week?
A: Cherry earns $2.50 x 4 = $10 after delivering four 5 kilograms of cargo per day. She earns $4 x 2 = $8 after delivering two 8 kilograms of cargo per day. So, her total earning per day is $8 + $10 = $18. Therefore, she will earn $18 x 7 = $126 in a week. The answer is 126.
Question: John is 15 cm taller than Lena and 6 cm shorter than Rebeca. If John has a height of 152 cm, what is the height of Lena and Rebeca together?
Answer: Lena is 152 cm - 15 cm = 137 cm tall. Rebeca is 152 cm + 6 cm = 158 cm tall. So, the total height of Lena and Rebeca would be 137 cm + 158 cm = 295 cm. The answer is 295.
Q: Sam bought a heavy safe with a combination lock. There were four rows with twenty gold bars per row arranged in the safe. If each gold bar is worth $20000, calculate the total worth of the gold bars in the safe.
A:
If there were four rows of twenty gold bars arranged in the safe, the total number of bars in the safe is 4 * 20 = 80 bars. Since each gold bar is worth $20000, the 80 bars are worth 80 * $20000 = $1,600,000. The answer is 1600000.
