After much debate, I decided to give up my full time job with an annual salary of \$50,000 in order to pursue my dream of an online business selling cookbooks. However, I will continue to work part time for the next 6 months prior to my business launch. I estimate the average retail value of each cookbook will be \$30 with the average cost of \$20.
The equation for demand is Q = 40,000-500P
Q = number of cookbooks sold per month
P = price of my cookbooks
Cookbooks sold at \$25 (Purple line)
Q = 40,000 – (500 * 25) = 27,500 cookbooks
Cookbooks sold at \$35 (Red line)
Q = 40,000 – (500 * 35) = 22,500 cookbooks
The red line on the demand curve depicts the price and quantity of the cookbooks if sold at \$30 apiece. Q= 40,000 – (500 *30) = 25,000 cookbooks

I estimate that the annual cost of this business will be as follows:
Technology (Web design and maintenance) - \$5,000
Postage and handling - \$1,000
Miscellaneous - \$3,000
Inventory of cookbooks - \$2,000
Equipment - \$4,000
