A catering company is setting up for a wedding. They expect 150 people to attend. They can provide small tables that seat 6 people and large tables that seat 10 people. Part 1: Find a combination of small and large tables that seats exactly 150 people. What combination would work? Show your work or explain your thinking.

Part 2: Write an equation to represent the relationship between the number of small tables, x, and the number of large tables, y, to seat a total of 150 people.

Part 3: Explain what the point (20, 5) means in this situation. Remember, coordinates are written in the order (x, y).

Part 4: Is the point (20, 5) a solution to the equation you wrote above? Explain your reasoning.
