A set of servers, that your project needs, has a daily lease cost of $500 for the first 20 days and the lease cost is reduced to $200 daily for any days after the first 20 days. If the team decides to purchase this set of servers, the investment cost is $11,000 and a daily operational cost of $75.

1. After how many days will the purchase cost be same as the lease cost?

2. Would this information be valuable for your project? if so how or why?
