Question

Sean’s class is selling boxes of popcorn to raise money for a class trip. Sean’s class paid \(85 for the popcorn, and they are selling each box for \)1. The function $y=x-85$ represents their profit y for each box of popcorn sold x. Find the zero and describe what it means in this situation.

Step-by-Step Solution

Answer

The required zero is represented by $x=85$ and it is representing that there is no occurrence of profit or loss.

Step 1. Determine the method which can be used to determine the required zero.

The equation that represents the value of x will represent the required zero.

Step 2. Determine the value of x .

Substitute 0 in place of y and perform addition of 85 on both sides of the provided equation.

$$\begin{gathered} 0=x-85 \\ 85=x-85+85 \\ x=85 \end{gathered}$$ 

Step 3. Write the conclusion.

The obtained value is same as the cost so there is no occurrence of profit or loss.
