[Question]: Olivia's insurance premium starts out at $50/month. It goes up 10% for every accident and $5/month for every ticket. If she gets in one accident and gets 3 tickets, what's her new insurance premium?
[Answer]: First find the increase due to the accident: $50 * 10% = $5. Then find the total increase due to the tickets: $5 / ticket * 3 tickets = $15. Then add both increases to the base price to find the new price: $50 + $5 + $15 = $70.
So the answer is 70.

[Question]: There are 10 books on the table. Two-fifths of them are reading books and three-tenths of them are math books. There is one fewer science book than math books and the rest are history books. How many history books are there?
[Answer]: Out of the 10 books, 10 x 2 / 5 = 4 are reading books. While 10 x 3 / 10 = 3 are math books. There are 3 - 1 = 2 science books. So, the total number of reading, math, and science books is 4 + 3 + 2 = 9. Thus, there is only 10 - 9 = 1 history book.
So the answer is 1.

[Question]: Paul is a chicken trader. One week he had 80 chickens in total to sell at the market. Before he left the farm, he sold his neighbor 12 chickens. At the gate, before the market opens, he got a quick customer and sold another 25 chickens. How many chickens was Paul left with to sell at the market?
[Answer]:
Before the market opened, Paul sold 12 + 25 = 37 chickens. So he had 80 - 37 = 43 chickens left to sell at the market.
So the answer is 43.
