You decide to start a landscaping company for the summer. In May, you buy up 3 lawnmowers, each worth $500 and an old trailer to haul them on for $1000. You spend $400 in marketing materials to identify and book contracts with your clients. Then, in June, July, and August, you and two friends mow lawns every week. After paying your friends, youre able to keep $1000 per month for each of those three months. Finally, at the end of August, you sell all your used equipment for $1500. Suppose, your required return for this project is 10%.
