(10 points) Suppose that initially a fund has $9,000. After 2 months the balance is $9,100 and $360 is deposited. After 7 months the balance has grown to $9,800 and an additional $1,200 is deposited. At 11 months, the balance is $11,400 and $4,800 is withdrawn. At the end of the year, the balance is $6,800. Find the dollar weighted return. (10 points) Suppose that initially a fund has $9,000.
