Question: John buys 6863 tickets for a raffle. Each ticket costs $15. If he gives 125 tickets to his friends and sells the rest for $20 each, how much money does John make?

John initially spends 6863 x $15 = $102,945 on buying the tickets. He gives away 125 tickets, so he is left with 6863 - 125 = 6738 tickets to sell. John sells these tickets for 6738 x $20 = $134,760. Therefore, John makes a total of $134,760 - $102,945 = $31,815 from selling the tickets and giving some away.

Math question: What is the largest prime factor of the number 6863?

To find the largest prime factor of 6863, we start by evaluating if it is divisible by 2. Since 6863 is an odd number, it is not divisible by 2. Moving on, we check if it is divisible by 3. By adding the digits (6+8+6+3), we get 23, which is not divisible by 3. Continuing with the next prime number, 5, 6863 is also not divisible by 5. Now, checking divisibility by 7, we sum the odd-placed digits and subtract it from the even-placed ones [(6+6+3) - (8)] which equals 7. Since 7 divides exactly into 6863, we divide it and obtain 980. Finally, testing divisibility by 7 for 980, we add the even-placed digits to three times the odd-placed digits [(8+0) + 3*(9)], which gives 35. As 35 is divisible by 7, we divide 980 by 7, resulting in 140. After all this, we conclude that the largest prime factor of 6863 is 7.

Math question: What is the sum of the digits of the number 6863 when multiplied by 5 and divided by 3, and then subtracted by the square root of the number 6863?

To find the sum of the digits of 6863, we add 6 + 8 + 6 + 3 = 23. Multiplying this by 5 gives us 115. Dividing 115 by 3 gives approximately 38.33. Now, calculating the square root of 6863 ≈ 82.84. Finally, subtracting this square root value from our previous result, we get approximately -44.51. Thus, the answer is -44.51.
