The Riverwood Paneling Company makes two kinds of wood paneling: Colonial and Western. The company has developed the following nonlinear programming model to determine the optimal number of sheets of Colonial paneling (x1) and Western paneling (x2) to produce to maximize profit, subject to a labor constraint: maximize Z= $25x1 - 0.8x1^2 + 30x2 - 1.2x_2^2

subject to x1 + 2x2 = 40hrs

Required:
Determine the optimal solution to this nonlinear programming model. b
