1. Given Q = 2P - 250, what is P? (write down P as a function of Q)

2. P and Q are determined by a system of equations. Solve for P and Q. Q = 2P - 250 P = 500 - Q

3. Given R = 300Q - 0.5Q2 . What is the first derivative of R (with respect to Q)? (Hint: Power Rule: If y = x n , then the first derivative of Y with respect to x is y' = nxn-1 )
