In this activity, students will choose three options from different menus to create their own business plan. They will need to decide on one item to sell, what store they would purchase to sell the item, and how they would like to advertise. The activity will walk students through writing an equation for the cost of starting their business and an equation for their revenue. Both equations are linear functions. Finally, students will use these equations to determine their breakeven point. An optional page is provided to let students get creative and design a logo for their business as well!
