Question: There are 60 ridges on a vinyl record. Jerry has 4 cases, each with 3 shelves that can hold 20 records each. If his shelves are 60% full, how many ridges are there on all his records?
Answer: Step-by-step reasoning process: First find the total number of records that can fit on all the shelves: 4 cases * 3 shelves / case * 20 records / shelf = 240 records. Then multiply that number by 60% to find the number of records actually on the shelves: 240 records * 60% = 144 records. Then multiply that number by 60 to find the number of ridges on all the records: 144 records * 60 ridges / record = 8640 ridges.
So the answer is 8640.

Question: Chad has 100 apples and each apple has different sizes and different price ranges. Each small apple cost $1.5, medium apple cost $2, and big apples cost $3. If Donny bought 6 small and medium apples and also 8 big apples, how much will Donny have to pay for all of it?
Answer: Step-by-step reasoning process: Donny was charged $1.5 x 6 = $9 for the small apples. He was charged $2 x 6 = $12 for the medium apples. And he was also charged $8 x 3 = $24 for the big apples. Therefore, Donny has to pay $9 + $12 + $24 = $45 for all the apples.
So the answer is 45.

Question: John runs a website that gets 30000 visits a month, for a normal 30 day month. He gets $.01 per visit. How much does he make per day?
Answer: Step-by-step reasoning process: He gets 30,000 / 30 = 1,000 visits per day. So that means he makes 1000 * .01 = $10 per day.

Question: Reina has three times the number of counters and four times the number of marbles as Kevin. If Kevin has 40 counters and 50 marbles, calculate the number of counters and marbles that Reina has?
Answer:
Step-by-step reasoning process: If Kevin has 40 counters, and Reina has three, the number of counters Kevin has, Reina has 3 * 40 = 120 counters. Reina also has four times the number of marbles that Kevin has, meaning he has 4 * 50 = 200 marbles. In total, Reina has 120 counters + 200 marbles = 320 items.
So the answer is 320.
