Solving Word Problems with Equations: Finding the Cost Equilibrium

The video tutorial teaches how to solve word problems by using equations with one variable. It begins with an example of choosing a cell phone plan and progresses to solving equations by isolating variables. The tutorial then presents a field trip cost problem, demonstrating how to set up and solve equations to find when two bus companies' costs are equal. The lesson concludes with a reminder to check solutions and avoid common mistakes.

Explain the steps taken to solve for the number of students needed for the two bus companies to cost the same.
