Question 9

What is the X-Intercept of the graph? What does it represent in the situation?

Accepted Answer

The x intercept is (40, 0). This means that if the coffee shop sells no cups of tea, they must sell 40 cups of coffee to meet their goal.

Answer

The x intercept is (0, 50). This means that if the coffee shop sells no cups of coffee, they must sell 50 cups of tea to meet their goal.
