An avid collector wants to purchase a signed basketball from a particular playoff game. He plans to put away 4% more money each year in a safe at his home to save up for the basketball. In the sixth year, he
puts $580 in the safe and realizes that he has exactly enough money to purchase the basketball.
To the nearest dollar, how much did the collector pay for the signed playoff basketball?

Suppose that an airline uses a seat width of 16.516.5 in. assume men have hip breadths that are normally distributed with a mean of 14.414.4 in. and a standard deviation of 0.90.9 in. complete parts (a) through (c) below. (a) find the probability that if an individual man is randomly selected, his hip breadth will be greater than 16.516.5 in. the probability is nothing. (round to four decimal places as needed.)
