The local botanical garden is setting up for a special event called "Music Mondays." They expect to have 100 people show up to the event and want to make sure that they have enough room for that many chairs. The first row has 8 chairs in it and each new row adds four chairs. How many chairs would be on the 5th row? Would 5 rows be enough to accommodate the 100 people?
