Question: Sally reads 10 pages of a book on weekdays and 20 pages on weekends. If it takes 2 weeks for Sally to finish her book, how many pages that book has?
Answer: Two weeks has 5 * 2 = 10 weekdays. Two weeks has 2 * 2 = 4 weekends. On weekdays, she reads 10 * 10 = 100 pages in total. On weekends, she reads 20 * 4 = 80 pages in total. So the book has 100 + 80 = 180 pages. The answer is 180.

Question: Isabela bought twice as many cucumbers as pencils, with both costing $20 each. If she got a 20% discount on the pencils and bought 100 cucumbers, calculate the total amount she spent to buy the items.
Answer: Isabela bought twice as many cucumbers as pencils, meaning she bought 100 / 2 = 50 pencils. The total cost for purchasing the pencils without the discount is 50 * $20 = $1000. At a 20% discount, Isabela paid 20 / 100 * $1000 = $200 less. The total amount of money she used to buy the pencils is $1000 - $200 = $800. She also bought the cucumbers at a total cost of $20 * 100 = $2000. The total cost for the items is $2000 + $800 = $2800. The answer is 2800.
