An industrial 3D printer that your team needs for prototyping mechanical parts has a lease cost of $300 per day for the first 30 days, and a lease cost of $200 per day for the next 30 days (Days 31-60). The lease cost is further reduced to $150 per day for any days after the 60th day. If the team decides to purchase this 3D printer, the investment cost would be $10,000. There would also be a daily operational cost of $100 if the printer was purchased outright. After how many days will the lease cost be same as the purchase cost? What does this tell you about what your team should do to save money?
