[Question]The average temperature in Orlando in a particular week was 60 degrees. If the temperature on each of the first 3 days in that week was 40, and the temperature for Thursday and Friday was 80 degrees each, calculate the total temperature of the remaining days of that week.
[Answer]If the average temperature of Orlando for the week was 60, then the total temperature for the week was 7 * 60 = 420 degrees. For the first three days of that week, the temperature was 40 degrees each day, totaling 3 * 40 = 120 degrees in the three days. The temperature for Thursday and Friday was 80 degrees each, a total of 80 * 2 = 160 degrees. The temperature of Orlando for the first five days was 160 + 120 = 280 degrees. The temperature for the remaining two days is 420 - 280 = 140 degrees. The answer is 140.
Q: 5,000 people live in a small town. 2,000 males live in that town and the rest of the population are females. Thirty percent of the female population wears glasses. How many females wear glasses?
A: There are 5,000 - 2,000 = 3,000 females that lives in the town. Since thirty percent of the female population wears glasses, 30 / 100 * 3,000 = 900 females wear glasses. The answer is 900.
Question: Alice has 20 quarters. She wants to exchange them for nickels and so she goes to the bank. After getting back from the bank, she discovers that 20% of the nickels are iron nickels worth $3 each. What is the total value of her money now?
Answer: A quarter is worth five nickels because .25 / .05 = 5. She gets 100 nickels from the bank because 20 x 5 = 100. 20 of the nickels are iron nickels because 100 x .20 = 20. 80 of the nickels are regular because 100 - 20 = 80. The iron nickels are worth $60 because 20 x 3 = 60. The regular nickels are worth $4 because 80 x .05 = 4. Her money is now worth $64 because 60 + 4 = 64. The answer is 64.

Diane made 1000 * 15 = $15000 in sales because she had 1000 customers each buy a $15 book. 37% of those customers returned their books, so that means she had .37 * 1000 = 370 returns. Each of those returns was for a $15 book, so she had 370 * 15 = $5,550 in returns. For her total leftover income, we subtract the returns from the sales and end up with 15000 - 5550 = $9450 in income. The answer is 9450.
