The local jazz band got a year long contract to play at a club on the last day of each month for a net $65 each appearance. After a series of unfortunate incidences, the band was forced to buy a new bass for $200 after their 3rd appearance and a new harmonica for $325 5 months after that. They started with only $10 in the band's account, but by the end of the contract they had $278! Calculate the dollar weighted rate of return
