Answer the following 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?
Step-by-step reasoning process: 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.

Answer the following question.
In my school, the number of students has increased by 20% this year. The number of students this year is 960. How many students were there last year?
Step-by-step reasoning process: Let X be the number of students last year. The number of students this year is X + X * 20% = 960. Combining like terms, we get X * 1.2 = 960. Dividing both sides by 1.2, we get X = 800 students.
The answer is 800.

Answer the following question.
Alexandra bought 8 magazines at the bookstore on Friday. On Saturday, she went back and bought 12 more. Sunday morning, she saw that the store was having a sale and she bought four times the number of magazines she did on Friday. Later that day she discovered that her dog had chewed up 4 of the magazines. How many magazines does she have now?
Step-by-step reasoning process: By adding Friday and Saturday, Alexandra bought 12 + 8 = 20 magazines. On Sunday she buys 8 * 4 = 32 magazines. Before her dog got to them she had 12 + 8 + 32 = 52 magazines. After her dog chewed up some she had 52 - 4 = 48 magazines.
The answer is 48.

Answer the following question.
Two white socks cost 25 cents more than a single brown sock. If two white socks cost 45 cents, how much would you pay for 15 brown socks?
Step-by-step reasoning process: Two white socks cost 25 cents more than a single brown sock, meaning a brown sock is sold at $0.45 - $0.25 = $0.20. The cost of buying 15 brown socks is 15 * $0.20 = $3.
The answer is 3.
