Question: Oliver has 10 $20 and 3 $5 bills. William has 15 $10 and 4 $5 bills. How much more money does Oliver have than William?
Answer: Oliver's $20 bills amount to $20 x 10 = $200. Oliver's $5 bills amount to $5 x 3 = $15. So, Oliver has a total of $200 + $15 = $215. William's $10 bills amount to $10 x 15 = $150. William's $5 bills amount to $5 x 4 = $20. So, William has a total of $150 + $20 = $170. Therefore, Oliver has $215 - $170 = $45 more than William. The answer is 45.

Question: Mr Fletcher hired 2 men to dig a well in his compound. They worked for 10 hours on the first day, 8 hours on the second day and finished the job on the third day after working 15 hours. If Mr Fletcher paid each of them $10 per hour of work, calculate the total amount of money they received altogether?
Answer: The total number of hours each worker works in the first 2 days is 10 + 8 = 18 hours. Since they completed the job in three days, each was compensated for 18 + 15 = 33 hours of work. Mr Fletcher paid each of the workers $10 per hour of work, meaning for 33 hours, each of the workers received 33 * $10 = $330. Since they were two workers, the total amount they received all together after each was paid $330 is $330 * 2 = $660. The answer is 660.

Question: A question and answer forum has 200 members. The average number of answers posted by each member on the forum is three times as many as the number of questions asked. If each user posts an average of 3 questions per hour, calculate the total number of questions and answers posted on the forum by its users in a day.
Answer: If each user posts an average of 3 questions per hour, the average number of answers posted on the forum is 3 times the number of questions which totals to 3 * 3 = 9 answers per. hour. In a day, with 24 hours, the average number of questions asked by each member is 24 * 3 = 72,. If there are 200 users of the forum, the total number of questions asked is 200 * 72 = 14400 questions in a day. At the same time, a member posts an average of 9 * 24 = 216 answers in a day. Since there are 200 members who use the forum, the total number of answers posted in the forum in a day is 200 * 216 = 43200. In total, the number of questions and answers posted on the forum is 43200 + 14400 = 57600. The answer is 57600.

Question: Tyrone empties his piggy bank and finds two $1 bills, a $5 bill, 13 quarters, 20 dimes, 8 nickels, and 35 pennies. How much money does Tyrone have?
Answer:
He has $2 in $1 bills because 2 times 1 equals 2. He has $5 in $5 bills because 1 times 5 equals 5. He has $3.25 in quarters because 13 times .25 equals 3.25. He has $2 in dimes because 20 times .1 equals 2. He has $.40 in nickels because 8 times .05 equals .4. He has $.35 in pennies because 35 times .01 equals .35. He has $13 because 2 plus 5 plus 3.25 plus 2 plus .4 plus .35 equals 13. The answer is 13.
