Last year, we hired 3 buses for the school trip. We had a total of 162 students and teachers who went on that trip and all the buses were full. This year we have 204 students. How many buses will we need? Will all the buses be full?
Given:
- Last year: 3 buses, 162 students and teachers, all buses full
- This year: 204 students
Step 1: Capacity per bus = 162 ÷ 3 = 54 people
Step 2: Buses needed for 204 people = 204 ÷ 54 = 3.78
Step 3: Since we can't have a fraction of a bus, we need 4 buses
Step 4: People in first 3 buses = = 162
Step 5: People in fourth bus = 204 - 162 = 42
Step 6: The fourth bus will not be full (42 < 54)
Answer: We will need 4 buses. No, all buses will not be full. The fourth bus will have only 42 people.
Explanation
First find capacity of each bus, then determine how many buses are needed for 204 people.
Solution Steps
Step 1: Capacity per bus = 162 ÷ 3 = 54 people
Step 2: Buses needed for 204 people = 204 ÷ 54 = 3.78
Step 3: Since we can't have a fraction of a bus, we need 4 buses
Step 4: People in first 3 buses = = 162
Step 5: People in fourth bus = 204 - 162 = 42
Step 6: The fourth bus will not be full (42 < 54)
