Mike repairs televisions. His revenue, in dollars, can be modeled by the equation y=25+30x , where x is the number of hours spent repairing televisions. His overhead cost, in dollars, can be modeled by the equation y=5x^2-10 , where c is the number of hours spent repairing televisions.
After how many hours does he break even?
Note: The phrase break even refers to the value where the two functions are equivalent.
