How do I figure and graph the emand curve?

You must five up your full-time job, which paid $50,000 per year, and you worked part-time for half of the year. The average retail price of the cookbooks will be $30.00 and their average cost will be $20.00 Assume that the equation for demand Q-5400-(153.3333*P) Q-the number of cookbooks sold per month P= the reatil price of books Show what the demand curbe would look like if you sold the books between $25.00 and $35.00
