Transcript text: Through market research, a business analyst has determined that the number $N$ (in thousands) of units of a new video game the company can sell is a function of the price $p$ (in dollars) of the game and is given by $N=-0.07 p^{2}+0.8 p+86$. (a) Find the ordered pair to complete the following table. Round to the nearest whole number. \begin{tabular}{|c|c|c|} \hline p & N & $(p, N)$ \\ \hline 10 & 87 & $(10,87)$ \\ \hline 15 & 82 & $(15,82)$ \\ \hline 20 & & ( \\ \hline 25 & 62 & $(25,62)$ \\ \hline 30 & 47 & $(30,47)$ \\ \hline 35 & 28 & $(35,28)$ \\ \hline 40 & 6 & $(40,6)$ \\ \hline \end{tabular} (b) Write a sentence that explains the meaning of the ordered pair $(25,62)$ in the context of this problem. If the price of the game is $\$$ $\square$ , the company expects to sell $\square$ games. (c) Graph the function for $p$ between $\$ 10$ and $\$ 40$.

Solution Steps

Step 1: Calculate the missing value in the table

To find the missing value of \( N \) when \( p = 20 \), we use the function \( N = -0.07p^2 + 0.8p + 86 \).

\[ N = -0.07(20)^2 + 0.8(20) + 86 \]

\[ N = -0.07(400) + 16 + 86 \]

\[ N = -28 + 16 + 86 \]

\[ N = 74 \]

The ordered pair is \((20, 74)\).

Step 2: Interpret the ordered pair (25, 62)

The ordered pair \((25, 62)\) means that if the price of the game is \$25, the company expects to sell 62,000 games.

Step 3: Graph the function

We need to graph the function \( N = -0.07p^2 + 0.8p + 86 \) for \( p \) between \$10 and \$40.

Final Answer

  • The missing ordered pair is \((20, 74)\).
  • The ordered pair \((25, 62)\) means that if the price of the game is \$25, the company expects to sell 62,000 games.
