Luke started working on a 1000-piece jigsaw puzzle. The first day he worked on it, he put together 10% of the pieces. On the second day, he put together another 20% of the remaining pieces from the first day. On the third day, he put together 30% of the remaining pieces from the previous day. How many pieces does he have left to complete after the third day?
Let's think: Luke started putting together, 1000 x 0.1 = 100 pieces. The next day, there were 1000 - 100 = 900 pieces left. Then he put together 900 * 0.2 = 180 pieces on the second day. So there were 900 - 180 = 720 pieces left. On the third day, he put together 720 * 0.3 = 216 pieces. Therefore, Luke still has 720 - 216 = 504 pieces left to complete the puzzle.. The answer is: 504.

Seth and Max were selling candy bars for a school fundraiser. Seth sold 6 more candy bars than 3 times the number of candy bars that Max sold. If Max sold 24 candy bars, how many did Seth sell?
Let's think: Let C be the number of candy bars Seth sold. 3 * 24 + 6 = C. 72 + 6 = C. C = 78.. The answer is: 78.

The Lion King cost 10 million to make and earned 200 million at the box office. If it earned a profit that was half of what Star Wars made and Star Wars cost 25 million to make, how many millions did Star Wars earn?
Let's think: The Lion King made 190 million in profit because 200 - 10 = 190. Star Wars made 380 in profit because 190 x 2 = 380. Star Wars earned 405 million because 25 + 380 = 405.. The answer is: 405.

Marsha works as a delivery driver for Amazon. She has to drive 10 miles to deliver her first package, 28 miles to deliver her second package, and half that long to deliver her third package. If she gets paid $104 for the day, how many dollars does she get paid per mile?
Let's think:
First find how far Marsha drives to deliver the third package: 28 miles / 2 = 14 miles. Then find how many miles she drives total by adding the miles for the three legs of her journey: 14 miles + 28 miles + 10 miles = 52 miles. Then divide her total pay by the number of miles she drives to find her pay per mile: $104 / 52 miles = $2 / mile.. The answer is: 2.
