I feel like it is really important for students to really understand what they are doing when they solve a system of equations. 175 North Beacon Street We can write the total cost per month as $$y = 49.95 + 0.05t$$. Therefore, we can find a linear equation for each plan relating $y$, the total monthly cost in dollars, to $t$, the number of text messages sent. _____ Graphing calculators will be used both as a primary tool in solving problems and to verify algebraic solutions. In addition, each text message costs 5 cent or \$0.05. To find the exact coordinates of each intersection point, we need to solve the corresponding system of equations. By determining the intersection point of two plans, students can make informed decisions. Plan B has a lower basic fee (\$29.95) than Plan A (\$49.95); therefore it starts lower on the vertical axis. (The lines are parallel.) Students analyze a cell phone bill to create a linear equation of how to calculate the bill. Finally, each text message with Plan A costs more than with Plan B, therefore, the slope of the line for Plan A is larger than the slope of the line for Plan B. In mathematics, a system of linear equations (or linear system) is a collection of one or more linear equations involving the same set of variables. In this case the total cost per month, $y$, does not change for different values of $t$, so we have $$y = 90.20$$, Plan C has a basic fee of \$49.95 even if no text messages are sent. Determine which plan has the lowest cost given the number of text messages a customer is likely to send. In two variables ( x and y ) , the graph of a system of two equations is a pair of lines in the plane.
