We would like to know how many of each there are a)Create a system of Linear Equations to represent the system b)Represent the system as a matrix equation c)Find the value of C so that there are infinite solutions and demonstrate that there are infinite solutions for this value of C graphing the two relationships by hand. (C is the total weekly payroll) d)Find the value of C so that there are No solutions (contradiction) and demonstrate that there are NO solutions for this value of C graphing the two relationships by hand. (C is the total weekly payroll)
