1. **State the problem:** We are given the function $$N = -0.07p^2 + 0.8p + 88$$ where $N$ is the number of units sold (in thousands) and $p$ is the price (in dollars). We need to find the missing value of $N$ when $p=20$ and explain the meaning of the ordered pair $(25, 64)$.
2. **Find $N$ when $p=20$:** Substitute $p=20$ into the function:
$$N = -0.07(20)^2 + 0.8(20) + 88$$
Calculate step-by-step:
$$20^2 = 400$$
$$-0.07 \times 400 = -28$$
$$0.8 \times 20 = 16$$
Now sum all terms:
$$N = -28 + 16 + 88 = 76$$
Rounded to the nearest whole number, $N = 76$.
3. **Complete the table entry:** The ordered pair is $(20, 76)$.
4. **Explain the meaning of $(25, 64)$:** When the price of the game is $25$, the company expects to sell 64,000 units (since $N$ is in thousands).
**Final answers:**
- Missing ordered pair: $(20, 76)$
- Explanation: If the price of the game is 25, the company expects to sell 64,000 games.
