How much is 100 times 3 divide by 10 plus 25 - 5?

To solve this expression, we follow the order of operations, which is Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right). First, we calculate 100 times 3, which equals 300. Then we divide that result by 10, giving us 30. Next, we add 25 to 30, resulting in 55. Finally, we subtract 5 from 55, giving us a final answer of 50.
