I have an assignment to create a poster for my economics class. I need to show mixed economy which i know is a mix of centrally planned economy and free market. I have no ideas but one. A column of the white house and underneath it a business license then underneath that (something else) then next to it an addition sign then something that is a good then an equals sign next to that ... equals mixed economy... yeah, i know not too good. does anyone know any ideas. or can at least tell me an example of a free market is
