[Question]: Chandra is going on a monster hunt. After a big storm, there have been lost monsters all around the castle grounds for the last 5 days. Chandra wants to rope them all up and return them to the swamps where they will be the most comfortable. On the first day she saw 2 monsters near the castle walls. Every day after that she saw double the amount as the day before. After 5 days how many monsters does she need to lead back to the swamps?
[Answer]: On the first day Chandra saw 2 monsters and on day 2 she saw twice that amount, 2 x 2 = 4 monsters seen on day 2. On day 3 she saw double that amount of monsters, 4 x 2 = 8. On day 4 she saw double that amount of monsters, 8 x 2 = 16. On day 5 she saw double that amount of monsters, 16 x 2 = 32. Altogether Chandra saw 2 + 4 + 8 + 16 + 32 lost monsters = 62 total lost monsters that Chandra needs to lead back to the swamps.
So the answer is 62.

[Question]: Jeff orders a Halloween costume. He has to put in a 10% deposit and then pay the rest when he picks it up. The costume is 40% more expensive than last year's costume, which cost $250. How much did he pay when picking it up, in dollars?
[Answer]: It cost 250 * .4 = $100 more than his old costume. So it cost 250 + 100 = $350. He left a 350 * .1 = $35 deposit. So he had to pay 350 - 35 = $315.
So the answer is 315.

[Question]: Every Monday to Friday morning, Alice walks 10 miles through a large grass field to get to school. To avoid the hot afternoon sun on her way home, she walks 12 miles through a forest. When she gets home on Friday, how many miles will she have walked that week?
[Answer]:
On Monday the total number of miles Alice walks to and from school is 10 + 12 = 22 miles. For the other 4 days, from Tuesday to Friday, she walks an additional 4 * 22 = 88 miles. The total number of miles she will have walked by Friday 22 + 88 = 110 miles.
So the answer is 110.
