Question

Problem solving (point of intersection)
You are considering changing your cell phone plan . Company A offered a flat fee of $40 plus 10cents for each additional min of use. Company B offers a monthly flat fee of $20 plus 15 cents for each additional min of use. What plan would you choose?
I came up with this equation, is that the one I want?
Y=.10x+40
Y=.15x+20
I'm stuck at that point
