Explanation:
To find out how many total students can go on the field trip if both buses are full, you should add the capacities of Bus 1 and Bus 2 together.
Bus 1 can hold 48 students, and Bus 2 can hold 28 students.
So, the total number of students that can go on the field trip if both buses are full is:
48 (Bus 1) + 28 (Bus 2) = 76 students.
