Algebra-1

To determine the maximum number of students allowed on the field trip, we can set up the inequality.

 

Let x represent the number of students.

 

The total cost for the field trip is given by:

Total cost = Fixed fee + (Cost per student × Number of students)

 

Given

The fixed fee is $320.

The cost per student is $7.

 

So, the total cost can be expressed as:

Total cost = 320 + 7x
