D Question 8 5 pts Solve the problem. Suppose that the demand function for x units of a certain item is p = 110+ 200 In(x + 5) where p is the X price per unit, in dollars. Find the marginal revenue. line O dR _200[x - [In(x +5) 12] dx x2 In(x +5) O dR _200 [x - (x + 5) In(x +5)] dx x 2(x + 5) O dR 200 = 110 + dx In(x + 5) O dR 200 dx = 110 + x +5
