The cost to print a poster is $4 per square foot plus a $2 flat fee. Juan’s teacher wants to print a poster for no more than $30. Which graph shows all the poster sizes, in square feet that Juan’s teacher can have printed for less than $30?
I don't know how to do the "equal to or less/more than" signs on a computer keyboard but, The final inequality would be something like : 30=/>4f+2 where f=7
