Math Question: If a company sold 400 products at a price of $50 each, what was the total revenue generated?

To find the total revenue, we multiply the number of products sold (400) by the price per product ($50). Total revenue = 400 * $50 = $20,000. Therefore, the company generated a total revenue of $20,000 by selling 400 products at $50 each.

Question: How many different ways can the number 400 be expressed as a product of two positive integers?

To find the number of ways, we prime factorize 400 as 2^4 * 5^2. We can choose any combination of these prime factors to form the two positive integers. Thus, the answer is the number of divisors of 400, which is calculated as (4+1) * (2+1) = 15. Therefore, 400 can be expressed as a product of two positive integers in 15 different ways.

Math question: What is the largest four-digit number divisible by 25, 10, and 8?

To find the largest four-digit number divisible by 25, 10, and 8, we need to find their least common multiple (LCM). The LCM of 25, 10, and 8 is 200. Now, we need to find the largest number less than 10000 (i.e., four-digit number) that is divisible by 200. By dividing 10000 by 200, we get 50 as the quotient. Thus, the largest four-digit number divisible by 25, 10, and 8 is 50*200 = 10000.
