Only need the answer for part b and c.

Posted this several times but none was related to my question.

Part B ask for the breakevn price in dollars using goal seek.

Part C ask for the price in dollars that maximize profit using data table that varies price from $50 to $400 in increments of $25.

Please help, will give positive feedback if correct. Thanks.

Eastman Publishing Company is considering publishing an electronic textbook to be $169,000. Variabke processing costs are estimated to be $9 per week. The publisher plans to sell single-user access to the book for $42. Through a series of web-based experiments, Eastman had created a predictive model that estimates demand as a function of price. The predictive model is demand =4,0006p, where p is the price of the e-book. (a). Construct an appropriate spreadsheet model for calculating the profit/loss at a goven single-user access price taking into account the above demand function. What is the profit estimated by your model for the given costs and single user access price (in dollars). (b). Use Goal Seek to calculate the price (in dollars) that results in breakeven. (Round to the nearest cent.) (c). Use a data table that varies price from $50 to $400 in increments of $25 to find the price (in dollars) that maximizes profit
