Answer:
3,750 cars.
Step-by-step explanation:
We are given that the equation:

Models the relationsip between <em>y</em>, the number of unfilled seats in the stadium, and <em>x</em>, the number of cars in the parking lot.
We want to determine the number of cars in the parking lot when there are no unfilled seats in the stadium.
When there are no unfilled seats in the stadium, <em>y</em> = 0. Thus:

Solve for <em>x</em>. Subtract 9000 from both sides:

Divide both sides by -2.4:

So, there will be 3,750 cars in the parking lot when there are no unfilled seats in the stadium.
