You are organizing a class trip to an amusement park. The cost to enter the park is $30. The cost to enter with a meal plan is $45. You have a budget of $2700 for the trip. The equation 30x+45y=2700 models the total cost for the class to go on the trip, where x is the number of students who do not choose the meal plan and y is the number of students who do choose the meal plan.

A line graph titled, class trip. The x-axis of the graph is labeled, number of students who do not choose the meal plan. The y-axis is labeled, number of students who do choose the meal plan. The line begins at a closed dot at ordered pair 0 comma 60 and ends at a closed dot at ordered pair 90 comma 0.

a. Interpret the intercepts of the graph.

The x -intercept indicates
students can go if
of them choose the meal plan.

The y -intercept indicates
students can go if
of them choose the meal plan.

b. Describe the domain and range in the context of the problem.

Domain:
to
students
