The flip-flop-alot company makes and sells flip-flops. they have one linear function that represents the cost of producing flip-flops and another linear function that models how much income they get from those flip-flops. describe the key features that would determine if these linear functions ever intersected.

Well if you start at zero for the cost and go to $10 which would represent the cost of one flip-flops and it goes up at a 10 to 1 ratio so your linear function for that would be f(x)= 10x 10 being the cost per production of flip-flops and x being the number of flip flops. then you would have the a $15 dollar sell rate or which would be a $5 extra rate. so then as you graph what would you get?
