Question: Marly has ten $20 bills, eight $10 bills, and four $5 bills. If she wants to change her bills to $100 bills, how many pieces of $100 bills will she have?
Answer: The ten $20 bills amount to $20 x 10 = $200. The eight $10 bills amount to $10 x 8 = $80. The four $5 bills amount to $5 x 4 = $20. So, Marly has a total of $200 + $80 + $20 = $300. Therefore, she will have $300 / $100 = 3 pieces of $100 bills. The answer is 3.
[Question]Donna cut her pizza into 12 slices and ate half for lunch. She ate 1/3 of the remaining pizza for dinner. How many slices are left for Donna's lunch tomorrow?
[Answer]Her pizza has 12 slices and she ate 1 / 2 of the pizza for lunch so that leaves 12 / 2 = 6 slices left. She eats 1 / 3 of the pizza for dinner, so she eats 1 / 3 * 6 = 2 slices. She had 6 slices and ate 2 slices, so that leaves her with 6 - 2 = 4 slices for tomorrow's lunch. The answer is 4.
Q: Due to the restrictions of Coronavirus, Mr. Trent, the local store owner, increased the prices of goods at his store by 15% each to make the same income he was making before. If buying an orange was $40 and the price of purchasing a mango was $50, calculate how much it costs in total now to buy ten oranges and ten mangoes at the new prices.
A: If the initial price of orange was $40, after the increase, the price rose by 15 / 100 * $40 = $6. The total price of buying an orange at the new price is $6 + $40 = $46. For the mango, the price increased by 15 / 100 * $50 = 7.5. The price of purchasing a mango at the new price is $50 + $7.5 = 57.5. To buy ten oranges it would cost $46 * 10 = $460. To buy 10 mangoes, it now costs $57.5 * 10 = $575. The total cost of buying ten oranges and ten mangoes is $575 + $460 = $1035. The answer is 1035.

[Question]While driving up a road, Philip passed through 5 intersections. 4 crosswalks marked each intersection with a total of 20 lines per crosswalk. Calculate the total number of lines of the crosswalks in the five intersections.
[Answer]If one intersection has 4 crosswalks, with 20 lines per crosswalk, there are 20 * 4 = 80 lines in all the crosswalks per intersection. If there are 5 intersections, the total number of lines in all the intersections is 80 * 5 = 400 lines. The answer is 400.
[Question]If Janet reads 80 pages a day and Belinda reads 30 pages a day, how many more pages does Janet read in 6 weeks?
[Answer]
First find the total number of days in 6 weeks: 6 weeks * 7 days / week = 42 days. Then find the total difference in the number of pages Janet and Belinda read each day: 80 pages / day - 30 pages / day = 50 pages / day. Then multiply the daily difference by the number of days to find the total difference in the number of pages they read: 50 pages / day * 42 days = 2100 pages. The answer is 2100.
