To determine the opposite of a given profit, you need to consider the profit's numerical value and its sign.
1. Recognize that a profit is indicated by a positive number. In this case, the profit is 35.
2. To find the opposite, change the sign of the number. The opposite of a positive number is the corresponding negative number.
3. Therefore, if the profit is 35, its opposite is -35.
So, the opposite of a profit of 35 is -35.
