Suppose that you open a mutual fund account with a deposit of $550. 4 months later, the fund balance is $625, and you withdraw $180. A year after the account was opened, your balance is $X. If the dollar-weighted and time-weighted yield rates were the same, what is the rate of return? (Assume simple interest for the dollar weighted calculation.)
