Five people can develop one software application in 13 days. If 2 people are suspended after the 4th day, how many total days will it take to complete the software application?
5 people x 13 days = 65 people days to complete
5 people x 4 days = 20 people days completed leaving
45 people days to completion by 3 people....... 15 days more to complete after suspension
total days 4 + 15 = 19 days total
