Question: If you divide the number 8000 by 4, add 500, subtract 1000, multiply by 3, and then divide by 2, what is the final result?

To find the final result, divide 8000 by 4 to get 2000. Add 500 to obtain 2500. Subtract 1000 to yield 1500. Multiply by 3 to acquire 4500. Finally, divide by 2 to get the final result of 2250.

Math question: What is the sum of all odd numbers between 2000 and 3000 which are divisible by 5?

To find the sum of all odd numbers between 2000 and 3000 divisible by 5, we first need to identify the odd numbers within the given range. Since odd numbers have a difference of 2 from the previous odd number, let's find the first odd number within this range, which is 2001. Now, we need to identify all odd numbers which are divisible by 5. The first such number is 2015, with a difference of 10 between subsequent numbers. Continuing this pattern, we will reach 2995. Using the formula for the sum of an arithmetic series, we have: Sn = (n/2) * (a1 + an), where Sn is the sum, n is the number of terms, a1 is the first term, and an is the last term. Here, a1 = 2015, an = 2995, and the common difference, d = 10. Hence, n = (an - a1) / d = (2995 - 2015) / 10 = 98. Substituting these values into the formula, we get Sn = (98/2) * (2015 + 2995) = 49 * 5010 = 245,490. Therefore, the sum of all odd numbers between 2000 and 3000 which are divisible by 5 is 245,490.

Math question: John receives $8000 as a bonus at work. If he decides to invest it in a savings account that offers a fixed annual interest rate of 4%, how much interest will he earn after 5 years?

If John invests the $8000 in the savings account with a fixed 4% annual interest rate, he will earn an interest of $1600 over a period of 5 years. The total amount in his account after 5 years would be $9600. To calculate this, the interest can be determined by multiplying the principal amount ($8000) with the interest rate (4%) and the time period (5 years). The formula for calculating the interest is: Interest = Principal x Interest Rate x Time. Therefore, John will earn $1600 in interest over 5 years, resulting in a total of $9600 in his savings account.
