Math Problem Statement

Write an equation and solve for x.

On Monday, 449 students went on a trip to the zoo. All 9 buses were filled and 8 students had to travel in cars. How many students were on each bus?

Solution

Let's break down the problem into an equation to solve for the number of students on each bus.

Problem:

  • Total students = 449
  • Buses = 9
  • Extra students traveling by car = 8

We know that the total number of students, 449, consists of those traveling by bus and those traveling by car. Since there are 8 students in cars, the remaining students must have traveled by bus.

So, the number of students traveling by bus is:

Students on buses=4498=441\text{Students on buses} = 449 - 8 = 441

Now, we divide this number of students among the 9 buses. Let xx represent the number of students on each bus. The equation is:

9x=4419x = 441

To solve for xx, divide both sides of the equation by 9:

x=4419=49x = \frac{441}{9} = 49

Solution:

Each bus carried 49 students.

Related Questions:

  1. How can we check the solution to ensure it's correct?
  2. What would happen if there were 10 buses instead of 9?
  3. How many more students would need to be accommodated if the number of buses increased to 12?
  4. If the number of students traveling by car was increased to 15, how would that affect the number of students per bus?
  5. What is the total number of students traveling by bus if 9 buses are filled and 10 students travel by car?

Tip:

To solve word problems like this, first identify the total number of students, subtract any exceptions (like the students in cars), and then divide the remaining students evenly among the buses.
