Question: The country of Belize had a 5 lane bridge that had 2000 vehicles passing through it every month. They decided to build a new bridge that had twice the capacity of the old one, and the number of vehicles passing through the new one increased by 60% more than the old bridge. If the bridges work concurrently for a year, calculate the total number of vehicles that pass through the two bridges.
Answer with step-by-step thinking: In a year with 12 months, the total number of vehicles passing through the old bridge is 2000 * 12 = 24000. The new bridge has a capacity of 60 / 100 * 2000 = 1200 more vehicles passing through it in a month than the old one. The total number of vehicles passing through the new bridge in a month is 2000 + 1200 = 3200. There are 3200 * 12 = 38400 vehicles passing through the new bridge in a year. Altogether, the two bridges have 38400 + 24000 = 62400 vehicles passing through them in a year.
So the answer is 62400.

Question: Ethan is reading a sci-fi book that has 360 pages. He read 40 pages on Saturday morning and another 10 pages at night. The next day he read twice the total pages as on Saturday. How many pages does he have left to read?
Answer with step-by-step thinking: Ethan read a total of 40 pages + 10 pages = 50 pages on Saturday. On the next day, he read a total of 50 pages x 2 = 100 pages. The total number of pages that Ethan had read is 50 pages + 100 pages = 150 pages. Therefore, Ethan has 360 pages - 150 pages = 210 pages left to read.
So the answer is 210.

Question: Elsie has a specific amount of wet wipes in a container in the morning. Throughout the day, she refills the container with 10 more wipes after using up 20. By nighttime, she only has 60 wipes left. How many wipes were in the container in the morning?
Answer with step-by-step thinking:
Let w be the number of wet wipes Elsie had in the morning. Throughout the day, she used w - 20 wet wipes. Once that happened, she had to refill the container resulting in w - 20 + 10 = w - 10 wet wipes. By nighttime, she had w - 10 = 60 wipes. So then, w = 60 + 10 = 70. She started with w = 70 wipes.
So the answer is 70.
