Math question: If you add 80 to a number and then multiply the result by 40, then subtract 3 times the original number, you get 3209. What is the number?

Let's represent the number as x. According to the given information, the equation is (x + 80) * 40 - 3x = 3209. Simplifying, we get 40x + 3200 - 3x = 3209. Combining like terms, we have 37x + 3200 = 3209. By isolating the variable, we subtract 3200 from both sides to get 37x = 9. Finally, dividing both sides by 37, we find x = 9/37. Therefore, the number is 9/37 or approximately 0.243.

Math question: What is the sum of the digits in the number 3209 when squared and then multiplied by its reverse?

To find the sum of the digits in 3209, we square the number to get 10269961. Next, we reverse it to obtain 16996201. The product of these two numbers is 174339791362761. Now, let's calculate the sum of the digits in this result. Starting from the leftmost digit, the sum is 1+7+4+3+3+9+7+9+1+3+6+2+7+6+1 = 70. Therefore, the sum of the digits in the squared number multiplied by its reverse is 70.

Math question: What is the sum of all the digits in the number 3209?

To find the sum of the digits in the number 3209, we add each digit: 3 + 2 + 0 + 9 = 14.
