Value of our company and why

During our presentation with the investors, we asked for a $18,000 investment for a 20% stake which specifically estimates our company at 90,000. We calculated this number by dividing 18,000 by .20%. Also, this value is determined by a bit of art. We based our company off the value of 90,000 by searching the market for competitors and researching our competitors products. For the first year, our company will take in a total of $129,558. the money we will receive from the investors will go towards everyday little expenses and some major expenses such as refiling inventory and some advertisement.
