Dalton's grade went on a field trip. A total of 195 students went on a field trip they used 7 vehicles some cars and buses to transport the students each car holds 45 students how many buses and cars does the school need to transport the students

Let:
- \( c \) be the number of cars.
- \( b \) be the number of buses.

Each car can hold 45 students, and the remaining students will be in buses.

We are given two conditions:
1. The total number of vehicles used is 7, which gives the equation:
   \[
   c + b = 7
   \]
2. The total number of students is 195. Since each car holds 45 students and buses hold the rest, the number of students transported by cars is \( 45c \), and the remaining \( 195 - 45c \) students must be transported by buses. This gives the second equation:
   \[
   45c + xb = 195
   \]
Here, \( x \) represents the number

Learn how to solve a transportation problem involving 195 students using cars and buses. The solution involves a system of linear equations to determine how many cars and buses are needed. Suitable for students in Grades 6-8.
