Linear Functions and Word Problems

In this episode of 'Mr. Boskin Does Some Math', the lesson covers various math problems including savings and expenses, graphing linear equations, and solving problems involving animals. The video begins with an introduction to the lesson, followed by solving a problem about Diego and Lynn's savings. It then moves on to graphing linear equations and finding intersection points. Finally, it tackles a problem involving chickens and cows, calculating the number of legs to find possible combinations.
