[Question]Maria's monthly salary is $2000. 20% of her salary goes to paying tax, and 5% goes to insurance. Also, a quarter of the money left after the deductions is spent on utility bills. How much money does Maria have after the deductions and utility bills payment?
[Answer]Maria's deduction for tax is 2000 x 20% = $400. Her deduction for insurance is 2000 x 5% = $100. Maria's total deductions is $400 + $100 = $500. After the deductions, Maria has only $2000 - $500 = $1500 left from her salary. Then, Maria pays $1500 / 4 = $375 for the utility bills. So, Maria has $1500 - $375 = $1125 after the deductions and utility bills payment. The answer is 1125.

[Question]Florida is starting a promotion where every car that arrives gets one orange per passenger. A family of 4 arrives and gets their oranges. They had planned to stop for a snack later where they would spend $15 in total, but now that they have the oranges they don't have to buy them at the stop. When they get to the stop they see that the oranges would've cost $1.5 each. What percentage of the money they planned to spend did they save instead?
[Answer]The oranges would've cost $6 because 4 x 1.5 = 6. The proportion of their original spending plan was .4 because 6 / 15 = .4. They saved 40% of the money they planned to spend because .4 x 100 = 40. The answer is 40.

[Question]Krystian works in the library. He borrows an average of 40 books every day. Every Friday, his number of borrowed books is about 40% higher than the daily average. How many books does he borrow in a week if the library is open from Monday to Friday?
[Answer]
The number of books borrowed on Friday is higher by 40 * 40 / 100 = 16 books. There are 5 days from Monday to Friday inclusive, so Krystian borrows an average of 5 * 40 = 200 books during that time. With Friday's increase in borrowings, during one week Krystian borrows 200 + 16 = 216 books. The answer is 216.
