[Answer]The first 7 days were $190. There were 11 - 7 = 4 days left. The additional 4 days were 4 * 30 = 120. And 190 + 120 = 310. The answer is 310.

[Question]Some friends wanted to make a road trip from New York to Los Angeles. They drove at a constant speed of 62 miles/hour, taking breaks of 30 minutes every 5 hours. Once in the city, they looked for the hotel for 30 minutes. If the trip took around 2,790 miles, how many hours will they have to spend to complete the trip to the hotel?
[Answer]At a constant speed of 62 miles / hour, they will drive 2,790 miles / 62 miles / hour = 45 hours in total. Every 5 hours they take a break, they will take 45 hours / 5 hours / break = 9 breaks. Those breaks will be 9 breaks x 30 minutes / break = 270 minutes in total. In hours, the breaks will be in total 270 minutes ÷ 60 minutes / hour = 4.5 hours. To find the hotel it took them 30 minutes ÷ 60 minutes / hour = 0.5 hours. In total, it will take 45 hours + 4.5 hours + 0.5 hours = 50 hours to complete the trip. The answer is 50.

[Question]Page collects fancy shoes and has 80 pairs in her closet. She decides to donate 30% of her collection that she no longer wears. After dropping off her donation, she treats herself and buys 6 more pairs to add to her collection. How many shoes does she have now?
[Answer]
She donates 30% of her 80 pairs of shoes so that’s .30 * 80 = 24 pair of shoes she donates. She had 80 shoes in her collection and donates 24 so that leaves 80 - 24 = 56 pairs of shoes. She now has 56 pairs of shoes and buys 6 more pairs so her collection is now 56 + 6 = 62 pairs of shoes. The answer is 62.
