George has opened a new store and he is monitoring its success closely. He has found that this stores revenue each month can be modeled by r(x)=x^2+5x+14 where x represents if months since the store opens the doors and r(x) is measured in hundreds of dollars. He has also found that his experience each month can be modeled by c (x) = x^2 – 4x + 5 where x represents the number of months the store has been open and c(x) is measured in hundreds of dollars. What does (r-c)(5)mean about George’s new store?
