[Question]Martin rings the small bell 4 times more than 1/3 as often as the big bell. If he rings both of them a combined total of 52 times, how many times does he ring the big bell?
[Answer]Let s be the number of times the small bell rings, and b be the number of times the big bell rings. We know that s + b = 52 and s = 4 + 1 / 3b. Substituting the second equation into the first equation, we get 4 + 1 / 3b + b = 52. Subtracting 4 from both sides, we get 1 / 3b + b = 48. Combining like terms, we get 4 / 3b = 48. Dividing both sides of the equation by 4 / 3, we get b = 36. The answer is 36.

[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]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. The answer is 62400.

[Question]Tommy's mother lets him ride his bike 2 blocks north of his block, 3 blocks east, 2 blocks west, and 2 blocks south. His friend's father lets his friend ride his bike 80 square blocks. How many times greater is the area his friend can ride in compared to Tommy?
[Answer]Tommy's area is 5 blocks wide because 3 + 2 = 5. His area is 4 blocks tall because 2 + 2 = 4. The total area is 20 square blocks because 5 x 4 = 20. His friend's area is 4 times bigger because 80 / 20 = 4. The answer is 4.

[Question]Marianne was 20 years old when Bella was 8 years old. How old will Marianne be when Bella turns 18?
[Answer]
Marianne is 20 - 8 = 12 years older than Bella. Bella will turn 18 in 18 - 8 = 10 years. So, Marianne will be 20 + 10 = 30 years old then. The answer is 30.
