Assume you have a lawn mowing business.You currently charge $15/lawn and can mow 5 lawns in an 8 hour day.You have more people asking for your service, but you cannot service them with your current resources.You can hire an assistant for $8/hour or you can rent a riding lawn mower (that will allow you to mow 7 lawns a day) for $100/week plus $25 for gas.You believe you can add 25 more customers.You only work 5 days a week.What is your best option?
