Reconsider the example of choosing the advertising budget for the VRX2000 that is presented in Section 1.4 There it was determined that the optimal level of advertising spending was $135,392 leading to a profit of $77,425 Now suppose that the component prices for the VRX2000 have been fluctuating The vatiable cost for producing the VRX2000 has now increased from $295 to $330 Due to the competive marketplace, VRX feels they cannot pass these costs on to the consumer, so the company plans to keep the selling price of the VRX2000 ot $400. Click here for the Excel Data.Elle Re-solve the optimization model for the VRX2000 considering the new variable cost a. What impact did the increased variable cost have (if any) on the best level of actvertising? Suppose instead that the varable cost for the VRX2000 decreases to $295.
