John owns a hot dog stand. He has found that his profit can be represented by the equation P(x)=-x^2+76x+84 where as P represents profits and x represents the number of hot dogs sold. How many hot dogs must he sell to earn the most profit? Bob owns a watch repair shop. He has found that the cost of operating his shop is given by C(x)=4x^2-200x+83 where c is the cost and x is the number of watches repaired. How many watches must he repair to have the lowest cost. A projectile is thrown upward so that its distance above the ground after T seconds is H(T)=-11T^2+308Tafter how many seconds does it reach it maximum height?
